History:
The La-7 was developed from the the La-5FN in 1943, using may light-alloy parts
as well as numerous refinements to the basic design, the La-7 became an outstanding
aircraft, more than able to take on the German fighters like the Fw 190 and
Me 109G.
However ways of gaining better performance were looked at and
like other Soviet aeroplanes the La-7 was fitted with deferent booster engines
two of which were jet engines (the other being a Glushko RD-1 liquid fuel rocket
engine fitted in the tail)
The La-7S was fitted with two Bondaryuk VDR-430 ramjets
under it's wings. Flown in September 1946 it managed a increase in top speed
of 64 km/h.
The La-7 PuVRD or PVRD had two RD-13 pulsejets fitted
under the wings, which gave it a top speed of 800 km/h at 8,000 m
