I would like to introduce a new kind of air-to-air missile for the game, ramjet propelled air-to-air missiles.
Today, I will be discussing the russian version of this kind of missile, the RVV-AE-PD, also known as the R-77-PD. The missile was a modernization of the original RVV-AE missile, which promised increased launch ranges against targets flying from low to medium altituides compared to the original RVV-AE missile by implementing a combined hybrid rocket-ramjet solid fuel engine . However, due to the lack of funds, the project was eventually cancelled after the completion of firing trials.
The R-77 (export name RVV-AE, NATO name AA-12 “Adder”) was developed by the Russian design bureau GosMKB “Vympel” in the 1980s as a medium-range air-to-air missile intended to arm the next generation of Soviet aviation fighters. Work on the RVV-AE family of missiles took place from 1982 to 1989, aiming to create a missile that could engage highly maneuverable targets and employ the “fire-and-forget” principle to reduce the carrier aircraft’s vulnerability during the intercept. What made the RVV-AE unique was the introduction of lattice (grid) fins, that improved control effectiveness and maneuverability while reducing size constraints for internal carriage at the cost of increased drag.
Components of R-77
R-77 missile layout:
1 – active radar-homing seeker
2 – compartment no. 2
3 – warhead
4 – motor/engine
5 – compartment no. 5
6 – laser fuze
7 – contact device,
8 – AB-72 autopilot
9 – PIM
10 – wing
11 – thermal electric battery
12 – electric control-surface actuator block
13 – rudder/control fin
With the creation of the R-77, the designers had finished their original goal - creating an air to air missile that employed the fire-and-forget principle that could be adapted to all modern planes in the Russian inventory - from the then state-of-the-art Su-27M/Su-35 to the lowly Mig-21. However, they were not satisfied with the range of the missile, as it was limited to a range of 80km which was similar to the range of the previous BVR missile that the soviets employed, the R-27R. So, they set out to improve the missile, and what they came up with was the RVV-AE-PD.
The creators of the missile decided to keep the same control system, warhead, and power supply as the original RVV-AE missile in order to keep the manufacturability and unification of the rocket for use of other complexes. The rocket rocket motor was changed from a solid-propellant single stage rocket motor to a solid fuel ramjet with controllable consumption of cruise gas generator. Air intakes were introduced to feed gas into the engine whilst also providing extra lift to the missile. The fins were also able to be folded at carriage position in order to be used in internal carriages of future fighter aircraft. This in turn, over doubled the range of RVV-AE-PD compared to original RVV-AE.
Testing of the missile was completed by 1999.
