Winged orbital launch vehicle. Year: 1988. Family: Winged. Country: Russia. Status: Study 1988. Vertical takeoff, ballistic re-entry, single-stage-to-orbit, Lox/Kerosene/LH2 tripropellant rocket engine powered, reusable launch vehicle. 550 tonne and 770 tonne gross lift-off mass versions considered. For the 550 tonne version, dry mass of the launch vehicle would have to be 68,700 kg / 18 percent of the gross, with payload 8,500 kg / 1.5 percent of the growth. Payload would range from 2000 to 10,000 kg depending on the uncertainties in weight growth of the design during development. As in other vertically-launched SSTO designs, this was considered too great a risk, and the air-launched MAKS was selected instead. Velocity loss during ascent estimated at 1665 m/s compared to 1168 m/s for MAKS (payload 3.1% of gross). Manufacturer: Molniya. LEO Payload: 8,500 kg (18,700 lb). to: 200 km Orbit. at: 51.00 degrees. Total Mass: 550,000 kg (1,210,000 lb).
