Little-known projects of the German aircraft of the Second World War

32
Despite the compilers' diligent work, the list of aircraft designed by Messerschmitt during World War II still contains significant gaps.


One of the specialists who had previously worked for MTT put at the disposal of the author some materials of that time, including technical characteristics and diagrams in three projections, which to some extent make it possible to evaluate designs of aircraft like P.1106, P.1107 and P.1108 and some presumably still completely unknown projects. At the same time, it still remains unclear whether these MTT aircraft projects were fully developed or it happened after the surrender of Germany. For one such project, in addition to certain technical characteristics and diagrams, the three projections also contain a detailed longitudinal section, but its typical designation is missing.

As was to be expected in such cases, some of the published technical specifications contradict data from other sources that have been available so far. The reason for this in the first place were numerous current changes that influenced the geometric and technical parameters.

Project P.1106
The P.1106 project is a miniature interceptor fighter (overall dimensions smaller than that of the Non-162), designed as a high-wing aircraft with one jet engine, V-shaped tail assembly and the front landing gear. The pilot's seat was to be located far behind in the aft fuselage. This project should have contained the minimum number of structural elements and should have been easy to manufacture.

Carrier plane
The wing was supposed to be free-carrying, two-spar, trapezoidal shape without transverse V. The ailerons should have been located at 75% of the length of the wing. Discharged outboard fuel tanks should have been suspended closer to the wingtips.

Fuselage
The fuselage was to consist of the front part with a central obliquely cut air intake, the lower section of the fuselage (it also had to be a motorcap) and the rear part with the pilot seat located far behind. The front of the fuselage was supposed to have an oval cross section, and the stern - close to the rounded cross section. The length of the fuselage was to be 6500 mm.

Chassis
The front wheel should have dimensions 540 × 160 mm. When cleaning, the landing gear had to rotate about its axis by 90 °. The wheels of the main chassis should have dimensions 800 × 220 mm. The chassis track width should have been 3600 mm.

Empennage
The tail of the V-shaped should consist of the keels and rudders, which should have been placed trimmers, and tips.

Power point
The power plant was to consist of a jet engine of unknown type.

weaponry
On the submitted drawings, weapons are not defined.

Little-known projects of the German aircraft of the Second World War

Technical data
Wingspan 6000 mm
Maximum length 6780 mm
The length of the fuselage 6500 mm
Maximum height 2850 mm
The height of the middle part of the air intake of the power unit 1080 mm
Swing V-tail 3060 mm
Chassis track 3600 mm
540 × 160 chassis front wheel dimensions mm
800 × 220 chassis main wheel dimensions mm

Figure 2 (illustration of the “main structural units and their joints”) shows the simplicity of the design of the aircraft and the ease of its maintenance.

Project P.1108
R.1108 was a long-range bomber project with four jet engines. This was supposed to be a flying-wing mid-flight. The wing should have a large sweep angle. The front landing gear had to retract in the backward direction. The main landing gear had to be removed in the direction back at an angle to the outer sections of the bearing planes.

The power plant of the four engines was to be placed in the wing of two turbofan engines in each console. The fuselage is made as a unit with the wing. In one of the first options, the air to the engines of the power plant recessed into the bearing planes was to be led through the air intakes located above the wing. In the second version, both the power unit and its air intakes were to be located under the wing. It is interesting to note that this project, at about the height of the air intakes of the power plant, on the upper surface of the wing provided for the installation of suction boundary layer slots (Absaugeschlitz). Fuel tanks were to be placed in the fuselage and in the wing.

If we carefully examine the rather detailed schemes made in three projections, then we can see the absence of any tail.



Fig.3 Schemes in three projections of the project P.1108 long-range bomber with four jet engines

Technical data
Wingspan 21700 mm
The length of the fuselage 12500 mm
Maximum length 15500 mm
Maximum height 3125 mm

Other flight technical data of this and subsequent projects, which will also be discussed in this material, are located in the “Project Overview” table.

The P.1108 project had another version, which, in contrast to the first, received a very small tail. Also, unlike the first version of this project, the second version was supposed to have significant changes, which also related to technical parameters:

Wingspan 20000 mm
The length of the fuselage 15700 mm
Maximum length 16250 mm
Maximum height 4700 mm
Chassis track 6000 mm
Dimensions wheel front rack chassis 935 × 345 mm
Wheel dimensions of the main chassis 1650 × 500 mm
Bomb load 1 × SC 2500, 2 × SC 1800



Fig.4 Two different types of air intakes in the project of a long-range bomber with four P.1108 jet engines: in version I, the air intakes of the power plant are located above the bearing planes; 1 scale: 100

Project P.1107
Early drawings and some technical specifications of this long-range bomber project, equipped with four turbojet engines, have already been published in another edition, and as in the case of P.1108 they deviate significantly from the table at the end of the article.

The project of a twin-engine Schwalbe fighter-bomber
In this project, made under the "flying wing" scheme, the engines of the power plant should have been located above and below the wing. Pilot cabin should be located between the upper air intakes of the power plant. Under the cab there should be a compartment in which the landing gear should be placed in the retracted position. The main landing gear had to be removed in the forward direction at an angle to the longitudinal plane of the aircraft. The ailerons and elevators were to be connected to the wing with the help of hinges; the fuel was to be located in the fuel tanks and in the wings in the fuselage and in the wings.





Fig.5 Schemes in three projections of the project of the twin-engine heavy fighter "Schwalbe". 1 scale: 100

What at first glance resembles a reverse, supposedly should have been either a brake flap or flap, which was intended for maneuvering during air combat.

Single-engine jet fighter "Wespe"
This mid-plane was represented by two variants with so many significantly different versions that they look more like two different projects.

In option I (“Ausführung I”), the pilot was to be located in the forward fuselage. The air intake of the power plant was to be placed on the side and below the fuselage. The front landing gear had to be located unusually close to the air intake of the power plant. When cleaning the front landing gear had to move in the direction of flight, the main rack had to be removed forward and at an angle to the longitudinal plane of the aircraft.



This project was inherent in the wing with a large angle of sweep, which was a single unit with the fuselage, and the rear elongated part of the fuselage with a V-shaped tail.

Option II (“Ausführung II”) was supposed to get swept high keel and stabilizer. In this way, this option was significantly different from option I. Presumably, the carrying planes of both projects should have been identical.



Fig.6 The project of single-engine fighter "Wespe". Scale 1: 100. The lower side view is a version that received the designation "Ausführung II"

Much more interesting was the project of the light fighter "Libelle"

The project of the light fighter "Libelle"
A single-seat fighter with a short egg-shaped fuselage, which should accommodate the pilot, power plant and a rather narrow chassis with a nose strut. The crescent-shaped form of the wing was an idea that first appeared on the same mid-plane of the Arado company. To improve the stability of the aircraft when flying at low speeds, the outer wing sections should have received slats. V-shaped tail assembly was to be far behind the fuselage itself. The tail unit should have been connected to the fuselage using a tubular section. Above all, this aircraft, with its wing span of 7 meters and the entire length of the 7,3 meter, should have been smaller in size than the well-known Non 162.



Fig.7 Schemes in three projections of the project of the Libelle light fighter. 1 scale: 100

Bomber-transport aircraft "Wildgans"
A six-engine jet aircraft with a take-off weight of 50 tons outwardly appears massive and in terms of form is nothing interesting. And here the air intakes of the power plant were to be located next to the cockpit. The exact location of the six engines is shown only in the side view. The front landing gear had to retract into the fuselage in the backward direction, the main landing gear had to retract in the direction back to the fuselage in the wing.

V-tail looked too small and flat. It is unlikely that such a tail could be sufficient for such an aircraft. Interesting in this project is the wing with an increased (dashed line) span.



Fig.8 Schemes in three projections of the project of the six-engine bomber-transport aircraft "Wildgans" with a take-off weight of 50 tons. 1 scale: 250

The project of a heavy fighter with a T-shaped tail
The type designation of this vysokoplan unknown. With its shape, this aircraft resembles other MTT projects, for example P.1112. The design of a heavy fighter was supposed to have two guns mounted in the fuselage, as can be seen in the longitudinal section. This detailed drawing suggests that this project was quite thoroughly worked out.





Fig.9 Schemes in three projections of the project of a heavy fighter with a T-shaped tail assembly (no typical designation)

Technical data
Wingspan 11800 mm
The length of the fuselage 10300 mm
Maximum length 12200 mm
The width of the inner section of the wing 2000 mm
The width of the outer section of the wing 1600 mm
Relative lengthening of a wing of 5
Wing area 28 m²
Take-off weight 7000 kg

Project overview (flight technical data calculated)



Notes to the table

1 For aircraft projects of the types “Schwalbe”, “Wespe” and “Libelle”, the specified weight loads are not related to the military, but to special versions of the aircraft data
2 Workload - the weight of all the loads that are needed to complete a task. It includes the materials consumed in the course of the assignment and other loads related to various materials, which are also used during the flight. Minimum amount of lubricating fluid, coolant, fuel, brake fluid, and servo-controlled oil systems.
Service load - the weight of the crew and the equipment removed after the assignment.
The load consumed during the flight is the weight of the materials consumed during the flight (fuels and lubricants)

        Thank! interesting link. good
        It is interesting in the table the line “total thrust of the power plant”, for “Wildgans” starting 12000 kgf, nominal 6000 kgf, is it afterburner or after takeoff half of the engines turned off? For afterburner, it’s kind of cool 2 times ... belay

    What would you like? In the USSR, there was still little technical documentation on developments not only in the field of aviation and rocket science, but also other types of weapons. The American and British commandosses literally took everything out of German scientific institutions. Their work was facilitated by the fact that American and German firms worked closely together before 2 1926nd and during World War II. Not only Opel belonged to the United States since XNUMX. Without Werner von Braun, American rocket science is unlikely to reach the heights it occupies now. You do not have to shout that we are ahead of the rest, but you need to think that developments and ideas Glushko, Brown, Mishin, Yangel come to their logical conclusion. We need new, breakthrough ideas, the development of new fuels, new technologies. You can write a lot about this and the order of Hitler, who banned new weapons development, if it could not be put within a year and about other developments that German firms conducted as part of their own research.

      No irony. Handbook: Missiles and people. Jet aircraft of the 3rd Reich. Herwig; Rode: Secret projects of Luftwaffe bombers. Chic; Meyer: Secret projects of Luftwaffe fighters. Hans-Ulrich Kranz books must be treated critically, because not everything is possible check or disagree with official facts. This is not all the literature on German developments in Germany.

    These are nothing more than technical art sketches, the fruits of a brainstorming session in the search for layouts and aerodynamic schemes. For example, how many search options did the same M-50 have, like other promising supersonic bombers, up to atomic ones. Therefore, they need to be treated in exactly the same way as unrealized fantasies.

    fantasies, fantasies, and the first jet-propelled aircraft they used and this is a fact. Rom14 stealth was invented in the Soviet Union, to be more precise, it wasn’t even stealth. And there was work in the field of studying radio waves where the author pointed out the possibility of creating machines invisible to radars. Then this uncle ended up in the United States. Because of the lack of demand in his homeland. About this even the film is poyuzay U. Tub. I watched for a long time. something with my memory has become here I remember here I do not remember.

      2.2 seconds is not enough even for a bomber.

      The Germans still B with their sweep wing. Yes, and much more. So, this is the circle of the modeller of the designer. Bring the project to mass production, you know, do not say stupid clever words.

    The Germans even had a suborbital bomber project. Take off in Europe, landing in Japan. On the way they bomb America. On the return route from Japan to Germany, the Urals are bombing.

      Actually not a project, but rather a concept. No detailed study. The temperature factor was not taken into account at all, in particular, the heating of the case when driving in hypersound. Conditionally taken at 500 degrees. In reality, many times more. Subsequent studies on a project based on the concept of a German bomber conducted in our country (it was supposed to use the German idea to create a carrier of nuclear charges) showed that such an apparatus simply could not be made in those days. In general, German designers, those who came to the Americans, in particular von Braun and others like him, were deceiving. Hoping to continue working in the states, they gave out some of their fantasies, which they had fun in their free time from their main job, for supposedly real projects being developed in Germany. Well, as they say - nothing personal, just business.

        Yes, with such a thrust-weight ratio, it’s too early to talk about anything significant. Even looking at the concept of a glider, there are already many questions about the stability of aircraft in flight.

    Yes, and now they are not.
    Here they usually write- "They stole the development from the Germans and took advantage of them." How many projects were taken out. It seemed that everything was there, take it and let it out, but ... for some reason, nothing similar appeared to anyone.
    The same tailless scheme. So many projects were developed by the Hans, and the Americans brought their B-2 only to the flight state in the 90s, and even learned that it only flies "on computers." Were computers of such power at the Hans? No. Would all these Arado 555 fly? No.

      So all this amazes me greatly. The Germans all flew (well, almost flew, there was not enough time), but the Allies only exploded, burned and sank. Okay, we Russians are stupid ( lol repeat ), but what about the brilliant Yankees and Saxons ??? What did they miss? Yes, and German experts, exported to the United States by hundreds in a compartment with tons of drawings and compositions of equipment, somehow did not help much.

      In the 40th, too, they said so-Little blood, a mighty blow. And then they retreated to Moscow. Do not throw Americans hats and become like Svidomo. NATO is a serious enemy. And even if you consider that the American a-priore soldier is weaker than ours, do not forget about the number of NATO troops.

    The article is interesting, informative, but the author spoke only about some German projects of combat aircraft. Most fully described about them in two books indicated in one of the comments on this article. The creative ideas of German designers were ahead of their colleagues in Europe and the United States, but not all of them could be realized, not only because the war was lost by Germany, but also for a number of technical reasons related to the lack of certain materials and technologies in the current state of aviation science by the end of the 40s.
    Today we can only compare what the Germans were right and what were the prospects for this or that project in the future, especially since the trophy developments were widely used by the countries of the anti-Hitler coalition in the post-war period and in some form or other have survived to this day. This applies not only to planes and missiles, but also to engines, the device of the main systems and assemblies, on-board devices, weapons, etc. etc.
    I advise you to read these books and think that they will be especially useful for students of aviation and other universities studying in the "Aircraft" profile. Without German developments, there would be neither Tu-95, nor B-1, nor MiG-15 and Saber, nor Mirage-3 and F -101, nor Buran and the Shuttle, and much more what left a mark in the history of aviation.
