"Assault
palne of ninetieth"
T-12
open article - Stormtrooper - 90(russian)
Work on "Assault-90" was started in 1984, the preliminary
design prepared in 1989. We
considered many options, both with one and two cabins, mostly
twin-engine.
As a result, the basis of the power plant was the "product 21"
- besforsazhny version of RD-33K. Take-off
weight in the TTZ was limited to number 18 800 kg, but the end of
the work has reached 21 500 - 21700 kg.
T-12 is a lifting body with two cabins, which are located
between the air intake ducts. Wing
negative sweep at the ends - containers REP. Left
on the flight cockpit is equipped with radar (probably variant radar
rearview IFI), the right - the operator - OLS. All
weapons - inside.

According to
the reference book "Jane" was supposed to build a machine based on
units serial Su-25.
In particular
research uses
the cabin, and wing keels, which have raised more questions than
answers. In theory, such
decisions could reduce the cost of production preparation.
Overall, the
project is similar to the British fighter helicopters SABA .

... Assault
on my basic combat performance was basically not to give the Su-25. After
reviewing the order of twelve or fourteen options was chosen scheme,
which allowed to achieve compliance with the TTZ. Yuri
was the lead designer Ivashechkina - chief designer of the Su-25,
converted to the time at OKB. Mikoyan.
The aircraft
was designed with the turboprop engine (power plant was completely
taken out of the draft of IL-114). Yielding
to the Su-25 for maximum speed, the new attack had (with the same
payload) great ferry range without drop tanks, the possibility of
basing on the ground of low density, could be applied to limited
areas and had a very low landing speed. Additional
features were stand-alone operation with a "hop aerodromes"
(technical staff and necessary equipment were transported by ground
attack plane), as well as the ability to perform transport and
special missions. Fuel
consumption for a typical execution of combat missions over the
Su-25 was less than five times.
Higher,
compared with the Su-25 aircraft survivability ensures reserving
booths "in the ball," the appropriate layout, as well as a low
vulnerability to missiles with infrared homing (due to a number of
layout and design decisions). According
to specialists NIIAS, capture missile seeker of "Stinger," there was
only a very narrow cone directed "back-up and away." High-speed
maneuverability to ensure effective application of combat work "on
earth" and, according to experts KB them. Kamov,
which are familiar with the project, made this plane "the worst
enemy of helicopters, which they could imagine." These
characteristics provide the use of aircraft as a "fighter UAVs",
which is very important in light of the significant expansion of the
use of unmanned vehicles in recent years.
It should be
particularly noted that all estimates are absolutely realistic - in
the "poster wars" that are so fond of some of the designers of the
period, the project of attack aircraft did not participate.
....
Unfortunately, the data presented below are based on calculations of
the mid-80s. However,
comparison of price data makes it possible for the initial
evaluation, and a calculation for the current conditions experienced
economist will be able to without any problems.
Customer
demands for economic characteristics of the aircraft were formulated
verbally and concerned a storm trooper, "to no more than a tank." This
problem was solved practically, if the cost of the tank at that time
was considered equal to 1 million rubles., The estimated cost of $
1.2 million attack plane now. For
comparison - the cost of being in a time of mass production of the
Su-25 was 3.5 million rubles.
.... Based on
the objectives, the design of aircraft was designed as
technological. Intelligent
solutions for design and layout problems caused by the fact that
almost inevitable at the stage of the project ties conflicts between
design and engineering departments at work do not arise.Project-based
attack aircraft Yakovlev Design Bureau. Mikoyan
later drafted a transport aircraft.
The project
was planned to use in the airborne equipment complex located only in
mass production or high degree of readiness for production samples. This
will allow, and now with little effort to link the side (perhaps due
to removal of the avionics are in order and taking off his share of
the airframe / engine aircraft).
Engines for
the attack aircraft were assumed to be TV-7-117C (with IL-114), but
it is now possible to use forced by resource-TV-3-117VMA SBM1 (with
AN-140) or VC-2500.
The integrated aircraft.
Past research on the prospective bomber T-4MS shown
numerous advantages of the integrated layout. These
developments would have been tempting to apply in practice and
in smaller-scale projects, such as fighter or attack aircraft.
E-model fighter jet was shown in the film in a series of
"Red Star" on the establishment of the Su-27. This
aircraft with a takeoff weight of about thirty tons. Relatively
thin center section could accommodate a class of engines AL-31F,
so I had to place four half as much traction.
Later, somewhere in the early nineties at an International
Conference on CAD representatives of the company, "Su"
electronic model showed a similar layout. At
first sight this type of attack an American A-12. In
reality, the picture without afterburner engines, practically
fit into the center section, the diagram of P-33D.
