The company also announced the cost of the work on the conversion of the vessel. Together with VAT, it will be 198,05 mln. Rub.

The newspaper notes that "one can only guess about the possible practical purpose of such modernization, because all scientific works will surely be kept secret."

This aircraft will continue the line of scientific vessels available in the Russian Aerospace Force.

"For example, on the basis of IL-76MD there is an aircraft carrier laser weapons A-60. This aircraft has a Skif-D laser installation, which can “hold back” the missile weapons and reconnaissance satellites of a possible enemy, ”reminds RG.

Attention on the console (after the engines) of the wing.

"The aircraft can be equipped with various free-fall bombs or radio beacons on 4 UBD-3DA beam holders." Bombing can be carried out both in automatic mode from the Kupol system and from the NKBP-7 collimator sight. At the moment, three Il-3 sides, which are based at the Migalovo airfield, are equipped with four UBD-76DA beam holders. "

[glasha3032]

The weight and aerodynamics of the bombs (50? 250 kg?) And the weight and aerodynamics of the engine are two different things. And how will the airplane behave when the hypersonic engine is switched on (instead of the regular? ..

Simply, this IL-76 is the property of the LII and has long been used as an LL (flying laboratory). The old programs are over, the new program (hypersound) has begun.

[glasha3032]

Clear . In Soviet times, this problem was solved simply - it must, so it will be manufactured as much as needed. Although the MO could transfer any aircraft suitable for suspension with a small residual resource.

Well, you have to start up products from some medium. No, it would be nice to involve a "native" carrier in this case, but you can't put a lot of measuring equipment into it. And then ... put it - I don't want to. Comfortably, we flew to the training ground, launched, watched, recorded ... so to speak in real time.

Launch of GPZ missiles (as with the B-52)? Since the IL-76 is not a carrier, there are no catapult pylons (AKU-2,3), the same thing did not happen.

Pylons are suspended, telemetry reception equipment is put in and out. The idea is good. Instead of building ground observation points, shove everything into a transporter, hang the product overboard and test it. Changing the starting height is easy, changing the weather is easy. You can take not one product, but a couple, with different assembly options.

in Australia, even students engage in hypersound:

Not surprising, but this projectile flies no more than 4 km. And slaughter remains even less.

... nope ... it’s only at the exit from the barrel ... and, further, air resistance and attraction ... the speed drops ... well, if you ordain a projectile into a plasma cloud controlled by a magnetic field ... then definitely ... so for the seed:

Currently, scientists need to understand in detail the mechanisms of propagation and change of a shock wave in nonequilibrium media. The most important applied task of such studies is the creation of the so-called “plasma envelope” of an aircraft — the inclusion in the aircraft control system of the technology of artificially created plasma flow on the wing, which can be controlled under the influence of a magnetic field, which will improve the aerodynamic performance of aircraft.

The scramjet E-57 consists of an axisymmetric three-hop air intake, a coaxial combustion chamber and an annular nozzle of a small degree of expansion. The shell and central body form an annular combustion chamber with special profiling along the length. On the walls of the chamber there are three hydrogen supply belts. The first feed belt with a niche flame stabilizer is located on the central body. Here, hydrogen is supplied to the combustion chamber through 42 openings with a diameter of 1,7 mm. The second belt with a step flame stabilizer is located on the shell, the third belt with a niche stabilizer is located on the central body. In the second and third zones, there are also 42 openings, but with a diameter of 2,1 mm. These belts are equipped with standard aircraft spark plugs for an electrical ignition system.

Man Do you understand in aerodynamics (even a bit)?
- if the aircraft was not originally designed for external suspension and missile launch (dropping bombs) this is not

Quote: Wedmak

almost none

not at all.
Let me explain: an airplane in flight has (almost always) an angle of attack, pressure under the wing (fuselage) is high from below, turbulence, etc. A rocket, a body having a linear length parallel to the air flow, the same with an angle of attack "flies" together with the carrier, which creates a lifting force.
SO:

it's "not for nothing" to knock down
- The problem is in turbojet engines, in air intakes and compressors: shock waves caused by the passage of a rocket, “turbulence”, rocket fuel combustion products, “entering” the air intake, can disrupt the normal operation of the compressor and, in the worst case, the engine will simply stop.

back in the 40-50s of the last century, on the first fighter jets, with unsuccessful placement of gun barrels relative to the engine’s air intake, the designers were faced with failures when firing: powder gases were drawn into the compressor, disturbed the flow around the turbine blades, as a result of sensitive engines stalled.

[glasha3032]

About the application in the form of a reset platform is not written. From the article you can understand what the hypersonic engine will be tested instead of the standard one (previously all other engines have experienced it like that) or is it just that the article is written clumsily? And then - the cost of revision is clearly not the cost of a new holder.

Wow! we got out of the bay !? Akuyut! it is not clear, but, most importantly, beautiful. the author, but what's the highlight?

[Mama_Cholli]

Not a specialist, but I will assume that it is possible that experiments are somehow connected with the difference in air velocity at the inlet of the turbojet engine diffuser (and not only with it, but also for example on purge mock-ups) and at the exit of the nozzle ...
Diameter, etc. ... I think that even taking IL-76 outboard air will be more efficient (cheaper) than a laboratory on the ground, where this air stream will have to be accelerated to its flight speed. It’s easier to cut a hole (width matters, so the plane is wide-body) and pick up what flies towards itself.

[Wedmak]

It’s easier to cut a hole (width matters, therefore, a wide-body aircraft) and pick up what flies towards itself.

Well, what do we get? Anyway, the flow rate at the inlet will be equal to the speed of the aircraft. And in order for the direct-flow dvigun to work, you need a minimum speed of 2-3 max.

A Boeing / AFOSR Mach 6 Quiet Tunnel wind tunnel was commissioned at Purdue University in the USA to study the movement of hypersonic devices in a laminar flow at a speed of 6 Mach - about 2 kilometers per second

The pipe is made according to the Ludwig scheme, has an output aperture with a diameter of 9,5 inches (more than 20 cm) and is designed to study the laminar-turbulent transition at a low noise level. With a duration of one reset in eight seconds and a cycle time of 1 hour, its cost is about $ 10 for one reset. The Reynolds number is about 13 million.

What interests me is not the flow rate at the input, but at the output. First, there is a decrease in diameter, and then again expansion. There is such a topic, density, temperature, speed, etc. depending on the size ...

When compared with the liquid in the pipes:
For example, at the same flow rates in two pipes of different diameters, the speed will be less in the pipe with a larger diameter.
So, for example, with the same water flow in the pipe dia. 150 mm will flow at a slower rate than in the dia pipe. 100 mm

[Wedmak]

Well yes, Bernoulli's law. Only I do not understand how this relates to the hypersonic laboratory at IL-76. Even if you squeeze the pipe into the eye of the needle, there will be no supersonic sound.
And the exit speed ... so on conventional turbojet engines it has already been studied up and down. The problem just lies in the speed of movement. With 4-5 swings and higher, air has great resistance even in the upper atmosphere. And to fly, you need to throw out combustion products even faster at the exit of their engine. Plus thermal and power loads. They are working on this. Well, while the PRD does not want to work correctly.

[Mama_Cholli]

I said that it was a layman. )))
Air flows around the wing in different ways, with different speeds from below and above the wing.
Is it possible to use this difference when taking the air flow from the places where the greatest difference in speed is?
It can be assumed that the flying laboratory will not work as a towing model, namely as a compressor for models.
Perhaps it’s not right, but once I read / saw (I don’t remember exactly) that one of our inventors suggested using a pump that uses nothing but the kinetic energy of the river itself to supply water from the rivers. Moreover, the idea was to increase the pressure in chambers turning over from the movement of the river, mounted on an axis, which was fixed on both banks of the river. The more chambers, the greater the pressure obtained at the outlet. Everything in the end is classified by oil companies. )))

write: Regarding your remark about the compression of the hole, but the output will still be an increase in speed. Or will it still not be?

[Wedmak]

Is it possible to use this difference when taking the air flow from the places where the greatest difference in speed is?

Efficiency is low. Moreover: a) a vortex forms in the place of the fence, b) the pressure immediately drops, since you remove part of the air from there.
By the way, I remember this effect used on the experimental devices of ECIP. They wanted to control the boundary layer on the fuselage with the help of hundreds of small holes in the skin. It seems like you could control the lifting force - more / less.
I think it’s easier. Or an observer, any carrier of experimental apparatuses.

Regarding your remark about the compression of the hole, but the output will still be an increase in speed. Or will it still not be?

It will, and if you add fuel there and set it on fire, we will get the same direct-flow engine in the simplest version.

And if you do not add anything, the flow rate at the output will certainly increase, he has nowhere to go, but the drag of the entire device will also increase.

Thanks for the reply.
If so, then the cost of remaking the aircraft is unclear. Could use a smaller machine (if an observer), I don’t think that it’s boring to carry tens of tons of equipment for observation.
To tow the same misunderstanding ... Why put a subsonic tug of product models? Could TU 160 be adapted for such a thing.

[Wedmak]

Yes, who knows. Observations are different again. And if not just a tug, but with the launch of a flight prototype? You can’t put a lot of fixing equipment on the Tu-160.
Here you can guess like a daisy, how many petals, so many options. And not the fact that we guess.

I agree. If the product is a fake, one thing, but if the flight prototype is another.
