Experts of TsAGI complete yet another stage in the research of the aerospace system

26 May 2015


Scientists of the Zhukovsky Central AeroHydrodynamics Institute have completed yet another stage in the research of the aerospace system intended for quick delivery of passengers and cargoes over intercontinental distances. The activities of the Russian aviation science centre are aimed at determining the effect of various fuel types on the exterior geometry and parameters of the aircraft. This aerospace system is a three-stage design and includes a twin-fuselage carrier aircraft, a hypersonic booster aircraft and an air-space vehicle equipped with liquid fuel rocket engine.

With the use of state-of-the-art design software, experts at TsAGI have generated a mathematical model of the aerospace system as a whole and of its individual components. The scientists have determined the parameters of the aircraft for three options of fuel for the hypersonic booster aircraft: kerosene, methane and hydrogen (with liquid oxygen as oxidant for all three options). The research has shown that the last option is the best among the three. Due to better energy characteristics the oxygen-hydrogen fuel option gives the possibility of raising the separation velocity of the air-space vehicle up to 4,100 m/s, and concurrently increase its takeoff mass up to 20.9 t. In this case the system will be capable of transporting up to seven people (five passengers and two crew members). By comparison, the use of methane or kerosene provides for the possibility to take no more than five people (three passengers and two crew members) on board the aircraft.

Valentin Buzuluk, the head of TsAGI’s department of aerospace equipment development prospects, has emphasized the particular importance of the twin-fuselage aircraft solution for the carrier vehicle. “This unique solution makes it possible to suspend rocket stages under the wing, which significantly simplifies ground operation of the system,” Buzuluk said.

“This work represents the future however, even today it is a strong contributor to the ‘piggy bank’ of scientific and technological potential,” explained Andrey Shustov, head of TsAGI’s department of aerospace equipment development prospects. “These research activities will enable scientists to take a considerable step forward on their way to develop environmentally acceptable aerospace and hypersonic systems that can make fast flights over vast distances.”
