The Florow 4302 ( Russian Флоров 4302 ) was a Soviet rocket aircraft project from 1946.
history
The development work was led by Ilja Florow and carried out in the same design office in which the BI-1 had already been developed. They began in 1944 as a result of a demand for accelerated development of aircraft with jet and rocket propulsion.
Project 4302 was a cantilever high- wing aircraft with unswept wings and wing tips that were pulled down by 45 °. Similar to the Bolchowitinow BI-1, the normal tail had two additional small end plates. In 1946 the first prototype 4302 / I was completed and flight tests began. Since it did not have its own landing gear, it had to be attached to a Tu-2 bomb plane, towed to a height and dropped. The landing took place on an extendable runner. An Issajew single-chamber engine with 10.8 kN take-off thrust served as the drive.
The second prototype 4302 / II was placed on a starting sled and could therefore start on its own. With this type, test pilot A. K. Pachomow reached 826 km / h at an altitude of 5000 meters in August 1947.
The third and last prototype got a more powerful showerkin-Gluschko RD-2M-3 two-chamber engine with 13.7 kN thrust and was also tested in 1947. As with the tried and tested at the same time I-270 by Mikoyan-Gurevich one came here to the conclusion that rocket-powered aircraft have a lot due to their limited engine burn time to short flight time to be used to effectively.
