Created by the OKB as the Zh to meet a 1945 requirement
for a rocket-propelled target defence fighter, the
I-270 was based broadly on the Messerschmitt Me 263, but was of a less radical configuration, featuring
a straight wing and conventional horizontal tail.
Adopting an ejection seat for the first time in a Soviet
fighter and having a wing of near-laminar flow profile,
the first of two prototypes was towed into the air
behind a Tu-2 - with ballast replacing the rocket motor
- in December 1946. Only the second prototype was to
be fitted with the rocket motor. This, the RD-2M-3V developed
by L Dushkin and V Glushko, was a bi-propellant
dual-chamber unit affording a total thrust of
1450kg of which the cruise chamber contributed
400kg. The cabin was pressurised and
proposed armament comprised two 23mm cannon and
eight RS-82 rockets. The second prototype flew under
power early in 1947, but was written off as a result of a
landing crash while being flown by an NII VVS pilot. Shortly afterwards, the first prototype was damaged in
a belly landing and was not repaired.

| Rico, rkocot(@)gmail.com, 22.06.2008 it's a nice plane, but almost in 100% it's a copy of german Messerschimtt Me-263 rocket plane whith went to soviet hands after 2WW, soviets called him also "¯ plane", all at all beautifull plane:) | | Kent Meyer, revkmeyer(@)yahoo.com, 06.12.2006 I'm working on a kit of the I-270. I have two questions: (1) what color would the seat belts have been; and (2) did the radio antenna post run through the rear of the canopy glass or was it set to the side of the rear canopy (like a Yak 15 and other aircraft of that era)?
Thank you! |
