For aircraft speeds which are much greater than the speed of sound, the aircraft is said to be

hypersonic

. Typical speeds for hypersonic aircraft are greater than 3000 mph and Mach number

M

greater than five,

M > 5

. We are going to define a

high hypersonic

regime at

M > 10

to account for re-entry aerodynamics. The chief characteristic of hypersonic aerodynamics is that the

temperature

of the flow is so great that the chemistry of the diatomic molecules of the

air

must be considered. At low hypersonic speeds, the molecular bonds vibrate, which changes the magnitude of the forces generated by the air on the aircraft. At high hypersonic speeds, the molecules break apart producing an electrically charged plasma around the aircraft. Large variations in

air density

and

pressure

occur because of

shock waves

, and

expansions

.

The accelerating block takes Zircon to the desired orbit, after which it accelerates to its maximum speed and moves to the target at an altitude of 30-40 kilometers, where the air density is minimal. Radars at this speed simply do not see him, anti-aircraft missile systems are useless. But, according to experts, the gigantic overloads, the rocket moves in a cloud of plasma. Super durable materials, overload resistant electronics are needed.

So I am assuming that high hypersonic speeds in low altitudes are able to form plasmas according to these 2 different sources in which some claim makes you completely invisible. So I guess 7th gen aircrafts will be called the true stealth gen fighters:highly_amused:. If only the mig-41 could go slightly faster than mach 4.3 :confused:

Roscosmos is developing a thermal barrier for hypersonic aircraft

Moscow. September 3rd. INTERFAX -

Roscosmos is developing radiolucent heat-shielding materials for radomes for hypersonic aircraft, according to the materials of the State procurement portal.

According to the materials of the portal, the state corporation is looking for a contractor for "developing a technology for manufacturing radiotransparent heat-protective materials for fairings of hypersonic aircraft based on volumetric frames made of refractory continuous fibers." The research work was called "Thor".


Work should be completed by September 2020. They allocated 346.9 million rubles.


In addition, Roscosmos is looking for contractors to develop "technologies for thermomechanical testing of composite materials in a wide temperature range with programmable thermal and mechanical loads that simulate the flight conditions of promising products of rocket and space technology" (code research - "Queen") and "technologies for producing high-temperature composite materials and a new generation of reinforcing fillers, pitch-based carbon fiber frames, ceramic SiC, SiCN fibers for promising rocket launchers space technology "(code research" Breakthrough-1 ").

There seems to be talks about a new business option for the MiG-29s and 35, discussed in relation to Malaysia. Russia would get the currently inoperative MiG-29 and sell in exchange the -35 at a reduced price.

This may in fact be quite interesting, if applied on a large scale:

- The customer would benefit from reduced prices and make some use of their otherwise obsolete or inoperative fighters
- MiG-35 would be sold easier than having to compete in equal terms with other competitors.
- Russia could use the old MiGs in a variety of ways: first, doing a basic overhaul and selling them at air forces in need of almost anything flying for very friendly prices, almost for free or in exchange of other "currency", be it economical or political, that can be of use. Given many of Russia's allies are under extreme economic pressure, it is not hard to find countries which would be among the ones who would benefit the most: Syria, Serbia, Iran, Cuba, Venezuela all would benefit from having the MiG-29 in a reasonable state either to have some form of fighter force at all or to boost it accordingly to the increased threats. Second, they could be upgraded heavily and sold to India for instance in order to boost their number of operational squadrons.

They would not make trillions but would load their repair factories, get business for the MiG-35, keep customers and get further profits through the maintenance of an expanded MiG fleet. Maybe it works, who knows.

There have been also comments that the contract with Egypt for the MiG-29M was finally closed at this year's MAKS.

Malaysia are going to buy MiG-35s? I thought they were buying Kuwaiti AF F/A-18s second-hand?

In the long run, a healthier domestic supplier base with income from deals with Western engine manufacturers will make Russian engine & aircraft projects more internationally competitive as well.

I doubt working with Western Engine manufacturer will make them competitive. and it will make them expensive without increasing reliability or lowering life cycle cost when things get complex or produced in lower quantities.
imagine maintaining 30 years old IL-76 if it was built with German engineering and not in same quantities like commercial fleet.

I doubt it. Previous reports indicated that these were inspected in Russia by an IAF team and found to be in pretty good condition. Partially completed airframes, not fly-worthy MiG-29s. But the IAF did also consider the option of buying Malaysian MiG-29Ns and putting them through the UPG upgrade. Don't know what happened to that after the initial interest.

One interesting thing to note on the MiG-35 is that its radome is smaller than that of the MiG-29M2 sold to Egypt and the MiG-29K. Looks like they weren't able to fit the full size AESA into the MiG-29M2 or MiG-29K radome, possibly due to a large back end?

Interview with UEC Chief on PD-14 , Military and other Engine programs

You make some of the best finds on Russian industry, Austin.

"

There are plans to increase the power of the PD-14 engine by increasing the fan bypass ratio and developing a PD-16 engine with higher characteristics on its basis."

Yup, seems like the geared version (PD-18R) is postponed for the foreseeable future. They'll take an easier approach to try to squeeze some more juice out of their design. To me, the PD-16 seems more definite than the PD-9/10, of which I'm skeptical of.

And with all of that helicopter engine development, Ukraine's MIC is screwed. The competition will kill them.

Cooling capacity.

The original Zhuk-A or AE was intended to have some 1100 TR Modules. But the cooling requirement is somewhat beyond the MiG-29's capacity. While the one we have now the current scaled back Zhuk-AE does not really meet the expectation.

Did anyone get any brochure on the AESA that the MiG-35 sported at MAKS 2019? What number of arrays, peak power, range for a fighter sized target, number of targets, etc.?

The F-35 fiasco for Turkey has really worked as a blessing for Russia. They're in full wooing mode, trying to get Erdogan to switch to the Russians as a big supplier.

MAKS 2019- Turkish President inspects Su-57 considers alternatives to F-35


...

Erdoğan became the first foreign leader to inspect the Su-57, which he did with defense minister Hulusi Akar and other members of his entourage. Their guides on the tour were Putin, Russian defense minister Sergei Shoigu, and United Aircraft CEO Yuri Slyusar. Surrounded by selected media members, he asked Putin whether Turkey can buy the Su-57 and received an affirmative answer. On several interactions with the press on August 27 and 28, Erdoğan said, “We came here for more than just a sightseeing tour. We will make steps after learning about the final decision [from Washington on the F-35]. The market where Turkey can acquire everything it needs is large enough." On another occasion, he said, “We want to proceed with the solidarity [with Russia] in many areas of the defense industry. This can be on passenger or fighter aircraft. We will continue with the spirit of solidarity.”

In his turn, Putin said that Turkish pilots are invited to undertake familiarization and evaluation flights in the Su-30SM. This type is a two-seat multirole fighter, as opposed to the Su-57 and Su-35 that are available only in single-seat versions. “When discussing combat aviation, we spoke of cooperation on the Su-35 and also about some possible work even on our newest Su-57. There are many other opportunities…and so we have also shown [the Turks] our modern combat systems as well as electronic warfare equipment. In my view, our Turkish partners are interested in many things, not only to buy but also to produce jointly. We are ready to cooperate in certain directions.”

On Wednesday the head of Russia’s Federal Service for military-technical cooperation with foreign countries, Dmitry Shugayev, confirmed Turkey's interest in procurement of “either the Su-35 or Su-57.” Clarifying Ankara’s viewpoint, foreign minister Mevlüt Çavuşoğlu said that Turkey would prefer to search for alternatives to the F-35 but would look for a new source to procure combat jets if the U.S. cancels F-35 shipments.

Russia’s minister for industry and trade, Denis Manturov, added that preparations for Su-57 serial production at Sukhoi’s KnAAPO plant in Komsomolsk-upon-Amur have been ongoing for several years and are about to be completed. Capacity is sufficient for the timely fulfillment of the Russian defense order for 76 placed at ARMY 2019. He further stressed that KnAAPO will assemble the Su-57 in parallel with the Su-35. An initial batch will rely on the existing AL-41 engines that will subsequently be replaced by next-generation “item 30” engines that have been in flight test since December 2017. Deliveries with these engines are expected to start in 2023. The Su-57 has passed flight tests using air-launched munitions carried in the inner weapon bays. According to the Tactical Missile Corporation, development of new weapons for the Su-57 is proceeding on schedule and, among other types, the fighter can fire the R-37M long-range air-to-air missile.

It's funny that another MiG-35 demonstrated on MAKS 2019 have had radme of normal size.

MiG-35 is really a strange progect.

I guess I was right after all about a certain idea I presented earlier when a certain user made a joke out of it:rolleyes:

https://topwar.ru/159438-predstavleny-proekty-jadernyh-reaktorov-na-avtomobilnom-shassi.html

Automotive chassis nuclear reactor designs presented

At the military-technical forum “Army-2019”, the research and design institute (NIKIET) named after N.A. Dollezhal presented projects of unique reactor installations, including on a car chassis. These are promising installations that, if implemented, will significantly expand the boundaries of peaceful uses of nuclear energy

"What installations are you talking about?

We are talking about promising designs of reactor plants of relatively small nuclear power plants: ATGOR, Shelf, Vityaz and UNITERM.

Earlier it was reported that such mobile nuclear reactors (auto nuclear power plants) can be used in areas with limited electric power resources - remote settlements. Mini-nuclear plants make it possible to reduce the cost of electricity, since the kilowatt-hours generated by a mobile reactor will cost about 1.5-1.7 times cheaper than the same kilowatt-hours produced by diesel-fueled diesel plants, which have to be brought in hundreds of km .

The reactor is equipped on a car chassis - in a protected capsule. According to some reports, it is planned to use an autonomous cooling system.

Today, NIKIET, which is part of Rosatom Corporation, acts as the chief designer of research reactors in the Russian Federation with a capacity of 100 MW (these are the SM-3, MIR, PIK units), the IBR-2 fast rector, and the MBIR multi-purpose fast reactor under construction."

Nuclear reactor powering FICs based radars with improved missile technology in the future will sure make some dangerous SAM designs. I wonder how greatly these power sources would enhance laser and microwave technology. Just another pain in the ass for future air forces to worry about and this could enhance coverage for their airforce as well.
