The H72L Dual-Mode Vectored Thrust Rocket-Based Combined Cycle Engine
The H72L was desinged by Soviet Nationalised Associates (SNA) - a government controled group of corporations; most notably: The Suhkoi Corporation. The H72L is a revolutionary engine known as a dual-mode, rocket-based combine cycle engine. The engine combines the use of a turbofan engine, a ramjet, and a scramjet engine. Using state of the art technologoy, SNA was able to design an engine that can obtain speeds not imagineable ten years ago. The DM-RBCC engine once reached an altitude of 35,000 ft. can initiate a process in which the two engines are inject with high octane, extremely refined rocket fuel. This potent mixture is carried onboard in a small seperate tank than the normal fuel chamber. Once the pilot initiates this process, the potent mixture - labeled HORF - is injected into the combustion chamber of the H72L engines. This forces the Su-91 to achieve a massive leap in speed. This leap is needed in order to begin stage 3. Stage 3 is the scramjet portion of the flight. Once stage 2 is completed, the airflow into the intake of the engines is being forced in at supersonic speeds causing the aircraft to accelerate into hypersonic speeds. This - plus several confidential components of the new H72L engine - transforms the lowly fighter engines, into high-velocity supersonic combustion ramjets.
The H72L is the successor to the fabeled H71K engine designed three years ago. With the virgin technology used in the Su-91, the Soviet Union has been able to leap forward in technology ahead of many western nations.
The Frame Issue:
Three years ago with the construction of the Su-80, a perfect design frame for which the RBCC could be effectively used was not practical nor affordable. But due to financial juggling, the SNA have developed a framework formed out of composite materials including steel, kevlar mesh, and a new form of construction known as HHLP Nanotechnology. Using these - among other - materials, a new design and framework was able to be constructed and manufactored relatively cheaply so that the Su-91 could be constructed.

Stealth
By merging several cunning edge stealth technologies including:
Vehicle shape. It has been known since at least the 1960s that aircraft shape makes a very significant difference to how well an aircraft can be detected by a radar. The Avro Vulcan, a British bomber of the 1960s, had a remarkably small appearance on radar despite its large size, and occasionally disappeared from radar screens entirely.
Use of non-metallic materials called composites for the airframe. Composites are transparent to radar, whereas metals reflect waves back to the radar transmitter if the metal happens to be perpendicular to the radar, or else the metal is involved in an unstealthy shape. If metals are to be used, some elements and alloys reflect less electromagnetic radiation than others.
Radar absorbing paint, especially on the edges of metal surfaces. In a similar vein, it is known that coating the cockpit window with a thin film of gold helps to reduce the aircraft's radar profile because radar waves would normally enter the cockpit, bounce off something random (the inside of the cockpit has a very complex shape), and possibly return to the radar - but if the gold reflects the incoming radar waves, most of the energy is likely to go straight up rather than back to the radar.
Technologies to reduce other signatures such as infra-red, visible, and sonic.
Technologies to reduce radar emissions. Infrared emmisions and sound aren't the only detectable emissions generated by ships or aircraft. The stealth vehicle must not radiate any energy which can be detected by the enemy, such as that of a height finding radar, terrain following radar or search radar.
Among those, is one of the newest Soviet stealth projects known as Project Guitar. The exact skematics for Project Guitar are not allowed to be released, but rumor has it, that by using some form of aucustic silencing, the sonic boom that gives away an aircraft, has effectively been minimalised to be a relatively unimportant variable in the safety of the mission.
Avionics
Among many avionic system used in the Su-91 is GPS, TACAN, VOR/DME, TL-RADAR, aircraft-engine integrationTL-Infa red, transponder units, digital fly-by-wire FCS, and intelligent FCS.A newer flight control system, called Intelligent Flight Control System (IFCS), is an extension of modern digital fly-by-wire FCS. The aim of IFCS is to intelligently compensate for aircraft damage and failure during mid-flight, such as automatically using engine thrust and other avionics to compensate for severe failures such as loss of hydraulics, loss of rudder, loss of ailerons, loss of an engine, etc.

Hopefully, within the next year, the Su-91 will be available to the international community. However, due to security restrictions, only extremely close allied nations - as of now - are being permitted to purchase the Su-91. Also, production rights are not available.
