In the USA, to reduce the cost of UAVs to overcome enemy air defenses, they decided to use the technology of V-1 engines

In the United States, options are being considered to reduce the cost of producing engines for promising drones and missiles. This is due to the fact that the number used by the US Army drones and missile weapons is growing exponentially, and there may be a situation in which the industry simply does not have the resources to meet the needs of the Pentagon.

To solve this problem in the United States, it was proposed to return to the consideration of engine options that were used in Nazi Germany. We are talking about the first variants of engines for the V-1 rocket. This is the PUVRD - pulsating air-jet engines, which, according to the United States, can be excellent for variants of new American drones and missiles of one type or another.

American columnist Thomas Newdick writes that the impulse technology, which was once implemented by the Nazis, "will help the United States to establish the production of inexpensive engines", including for a new UAV.

Meanwhile, it became known that the US Air Force Armaments Directorate signed a contract with the WEC (Wave Engine Corporation) to develop and demonstrate a false air target with a pulse jet engine. It is a versatile platform launched from an aircraft carrier. Usually abbreviated as VALP. At the moment, $ 1 million has been invested in the development. It is planned that such unmanned vehicles will be launched from fighters, for example, from the F-16. Such devices are mainly planned to be used to overcome enemy air defense systems.

An unmanned aerial vehicle is dropped from an aircraft, misleading the radars of anti-aircraft missile defense systems. At the same time, both the drones themselves and the aircraft can strike targets.

It is believed that the technology that was applied back to the V-1 will allow for the mass and low-cost production of engines for such vehicles in the United States.

Aha But it would be better if they relied on the V-2 technology (Vergeltungswaffe-2) whose engines ran on the purest alcohol.

In this situation, I think, our air defense personnel would hone their professionalism to such an extent that they would "land" the UAV without damaging the fuel tanks

[alex neym_2]

As one friend of mine who worked at a distillery said: "Alcohol is a good help to the household budget"! Well, and in the army, for the l / s, even more unaccounted for ... how much he will be sent from there, no one knows ...

[DmitryMsk]

Our air defense officers already receive alcohol for maintenance.
In general, alcohol was relevant in the 90s, when it was sad with vodka (
Now the air defense officers would have appreciated the missiles on Brandy, Viskami or Calvados))

Well, not that slow. Detonation engine option. As the fuel depleted, it accelerated to 800 km / h and the propeller-driven fighters could no longer catch up with it. The level of automation of that time was not enough to be used with at least some kind of combat effectiveness. At a new "round of development" and the engine "shaman", well, there is enough automation now ... And turbojet engines for cruise missiles are expensive.

Maybe they'll be pissed, but if I'm not mistaken, the loud sound and low speed are organic shortcomings of the PUVRD.

You are wrong. Loud sound bothers whom? And the speed of the V-1 was limited by poor aerodynamics and the overload of the projectile aircraft. Almost a ton of explosives. I wrote. At the end of the trajectory, when the fuel was almost running out, the fighters of those years did not catch up with it, and therefore tried to intercept earlier. The target is small, low-flying, the anti-aircraft gunners were afraid to shoot at it. Because he often fell next to their positions. And exploded ...

What does not interfere with a flying bomb during the war, it interferes with the UAV in peacetime: nobody canceled the noise norms. Yes, and a loud sound fundamentally subsonic target does not unmask the acid.

You wrote, and I checked, and so, PuVRD, according to the wiki, is limited in speed to 250 ms. what is fast for the WWII period is not very good for the 21st century.

For the trick, what is the difference, loud or slow? The main air defense detects and fulfills, and this time and ammunition.

This is precisely the characteristic and loud sound that can serve to separate "the lambs from the goats."

Maybe now the sound can be heard on the radar, but during the years of my service as a radar operator, unfortunately, there was no such function. And the concept of a false target was.

In "your" years already or may not have existed, but somewhat earlier, acoustic air defense locators were very widely used, so why not appear a little later, additional acoustic sensors to the radar and OLS.

[Fedor M]

In the calculations, they are not suckers, they will be able to distinguish between f16 and a blank

[PROXOR]

You didn't get the message. The task of these missiles is to create a swarm that will deplete the stocks of missiles from the defending side. The second wave will already be tomahawks, the third bomber aircraft. For the defending side, he will learn how to correctly select targets.
800 km / h - Shilka 4M will easily cope with them up to heights of 3 km. And to recharge it many times faster and cheaper than at least the same BUKs and TOPs.

The characteristic and loud sound of the PUVRD is just an additional factor for confident selection.

The PUVRD is organically incapable of delivering more than 800 km / h (according to Vicki).

How will you classify it by sound at a distance of at least 20 km from the first echelon.

ADDITIONAL factor, at 10 km distance is already quite working.
And yet, in the article, this motor is referred to as a remote control for a UAV, and not only for false purposes, so this is the main question about a loud sound specifically for a UAV.

Well, is it logical to think ?! What is this propulsion device for (which is outdated, easily destructible) on a modern UAV?

Exactly!!! Barrage ammunition, false target. Well eptit. Recently there was an article about new tactics being developed by the striped against our air defenses. These will be disposable items like the V-1.

The main disadvantage of the PUVRD is almost impossible to control the thrust.

But it's not a fact that it is much better, the efficiency of such an engine is still ...............

Wernher von Braun had nothing to do with the development of the V-1.

The engine (PuVRD) was developed in the late 1930s by the designer Paul Schmidt.
And the first practically working prototype of the Argus-Schmidtrohr engine (As109-014) was created by Argus Motoren in 1938.

[rotmistr60]

The US is considering options to reduce the cost of producing engines for promising drones and missiles

With a military budget of over 700 billion with a prospect of 1 tril. decided to save money on engine production. Maybe it will be more effective to reduce a couple of bases and immediately find money for engines? But it is their own business to use German technology from the 40s of the last century or fly on a broomstick.

[Blackmokona]

The author simply does not see the difference between the type of jet engines and the models of jet engines.
This is how the US is going to use internal combustion engines that were developed over 100 years ago. In his new armored vehicles.

[riwas]

And ours have already prepared an answer. Sniper pairs of special forces of the Southern Military District began training in firing at drones and ground targets from a helicopter patrolling in the air. The principle of fighting "flying" snipers with enemy unmanned aerial vehicles is simple. Radar stations detect drones long before approaching restricted areas or military installations.
Information about the detected target is sent to the control panel of the duty forces, then the coordinates are transmitted to the sniper group, after which the snipers are quickly landed in the Terminator and taken off. "The helicopter crew is required to work out and coordinate with the sniper the moment of hovering and maximum immobility of the vehicle in order to fire a shot at the target," the military department stressed. Helicopter and sniper training takes place in the skies of the Rostov Region, Kuban, Stavropol Territory and the republics of the North Caucasus. It is planned to train 400 servicemen in the new method of shooting.

Snipers against UAVs? So that like a squirrel in the eye ?

Is it necessary? It would be better to take the same number of more or less trained in shooting recruits, give them "shotguns" and put them on the same helicopters to shoot small drones ...

A relatively large UAV, for example "Bayraktar", of course you can't take from a shotgun, but using snipers against them is also stupidity.

[alex neym_2]

PUVRD is a simple and cheap engine, which SyuT people used to assemble on their knees, but used it as a propulsion unit on models of racing boats ... it turned out to be a great thing ...

[113262a]

Well, not the SYUTOVS themselves, but their instructors, and not on their knees, but on a decent machine park and according to detailed drawings. And with good roll or spot welding.

[alex neym_2]

Well, what are you, enough of a 16K20 type lathe and a stainless steel brand, for example, 12X18H10T, both rolled with a diameter of 50 mm and a sheet of 0,5 mm of the same material ... the rest is a matter of technology and ingenuity ... we do not make an engine for a projectile. ...

[113262a]

No, from 0,5 it will definitely not fly! Even the cord one! The pipe and combustion chamber are 0,15-0,25, the valve is from 65G-0,1-0,15, the valve body is from D-16T. ... I made a dozen of them then! The book was awesome - YEARS, MODEL!

[Nikolaevich I]

Well, the PUVRD on the UAV is no longer a curiosity! Someone, perhaps, remembers that for the MLRS "Smerch" an eres with "stuffing" in the form of a UAV with a PuVRD was once developed ... Several modifications of the UAV with a PuVRD are offered by Enix for different "occasions"! You can see something

By the way, modern mini-PUVRDs should not be considered "copies" of the FAU-1 engines! Both among the turbojet engine and among the PuVRD there are varieties! (If memory serves, then there are 3 types of PUVRD!) Most of all I was surprised by the Americans! Indeed, at one time they relied on mini-turbojet engines ... developed mini-turbojet engines for NLOS-LS AT missiles ......!

At the same time, the Americans spoke very dismissively about the "hobby" of the Russians for "old things" - PuVRD! The Americans believed that they could get relatively cheap turbojet engines using gas turbines and compressors that were mass-produced for turbocharged automobile engines!
And now ... "on you"! It turned out that the Shtatovites also considered the PuVRD the best "candidate" ?? Niht Andestend!

[Daria33]

With minimal cost, using the technologies of the Second World War, they will make promising drones and missiles, and then sell them to unpromising countries at exorbitant prices ... Business!

[SovAr238A]

Damn!
How translators misinterpret and distort the news ...

In fact, the news sounds like this:

Wave Engine Corp. is a dedicated group of scientists, engineers and former Fortune 500 executives who develop and use propulsion, acoustics and combustion control technology to develop next-generation aircraft and propulsion systems.
Those. cool enough laboratory.
Versatile Air-Launched Platform Technology from Wave Engine Corp. allows to reduce the cost and complexity of jet propulsion by an order of magnitude, which makes it practical for a wide range of aircraft platforms, for which a jet engine was previously prohibitively expensive.
Versatile Air-Launched Platform - Patented in 2018.
In 2019, DARPA allocated $ 3 million to create working prototypes.
And in 2020, they started testing.
Now, based on the results of the first tests, the US Department of Defense has already assessed the potential and started financing activities and issued 1 million.
The aviation industry has long been at a standstill due to the lack of high-performance engines for small aircraft, and Wave Engine Corp believes it can remember this niche.

And here the Fau missiles, if the Americans have a new patent ???
Have you just tied an impulse taxiway and at least the grass will not grow further?
And in fact - the implementation of this project can really turn the whole future of aviation!
Small-sized, powerful, scalable, super-cheap taxiways - will allow hundreds of thousands of riveting various flying devices.

[Waltasar]

Load more of these missiles into the B-52 and fire a bullet from a safe distance before overloading the air defense. Some cheap pacifiers, others with a warhead.
I do not like it.

[Reserve buildbat]

They will begin to stamp pipes, as in the V-1, the same ineffective, but at a price not in hundreds of marks in 1944, but in tens of thousands of dollars apiece in 2022.
