Cholod Laboratory
The hypersonic flight Rapid laboratory "Cholod" ( Russian Гиперзвуковая летающая лаборатория "Холод" "cold" ) was one of the ZIAM developed Soviet / Russian unmanned aerial vehicle, with the world's first hypersonic ramjet to be tested.
For the initial acceleration of the "Cholod" a by the air defense system served S-200 derived experimental rocket 5W28EUD ( Russian 5В28ЭУД , ЭУД stands for Experimental Well Utschebno-Dejstwujuschtschaja), was mounted in the place of the warhead, the hypersonic engine E-57 Amendment. The tank for the liquid hydrogen was built into the experimental rocket. In ramjet mode, the engine pulled the rocket while the exhaust gases flowed around it.
history
The "Cholod" program, which started in the Soviet Union at the end of the 1970s, was initially canceled after the collapse of the Soviet Union and lack of funding and was later taken up again - partly financed by the USA and France. The project results were used in the design of the Boeing X-43 .
From 1991 to 1999 five test starts took place in Sary-Schagan . The maximum speed achieved was 1855 m / s ( Mach 6.49), the altitudes 22 to 35 km. The maximum working time of the ramjet E-57 was 77 seconds, with the engine being able to be switched off and on several times.
