49M
Russian manned spaceplane. Study 1981. The 49M was an application of the system 49 air-launched design concept, but with a larger carrier aircraft. The orbiter mass was 28 metric tons in orbit, including a 9 metric ton payload in a 8.

0 m x 3.3 m diameter payload bay.

The system would have a 770 metric ton gross takeoff mass. The orbiter/rocket stage combination weighted 370 metric tons. The tripropellant single rocket stage was equipped 1 x NK-43 / 11D112 engine burning Lox/Kerosene and 2 x RD-57 / 11D57 engines burning Lox/LH2. The orbiter could have one or two crew, and was designed for 100 reuses. Development costs for the new heavy lift aircraft and larger orbiter would be too high, and the design was abandoned in favor of the Bizan concept.

Associated Launch Vehicles
  • System 49 Russian air-launched winged orbital launch vehicle. The Spiral project was not cancelled with the decision to proceed with the large Buran spaceplane. Instead flight test of the orbiter continued but the launcher design was rethought. The ambitious Mach 4 air-breathing first stage was abandoned. Instead the rocket stages and the manned Spiral orbiter were mounted on the back of an An-124 subsonic transport. This concept would evolve through the Bizan concept to the MAKS of the 1980's, which reached the hardware development stage. More...
