TsAGI completed a test phase of crew transportation spacecraft Orel

October 29, 2019

Zhukovsky TsAGI (Central Aerohydrodynamic Institute, which is a part of the Scientific Research Center Zhukovsky Institute) has completed a phase of testing on the Crew Transportation Spacecraft (CTS) Orel, which is being developed at the Korolev RSC Energia (which is a part of the State Corporation Roscosmos).

The studies focused on the aerodynamic properties of the parachute container cover during its separation from the spacecraft re-entry vehicle. Separation of the parachute container cover is directly involved in the deployment of the reentry vehicle parachute system, therefore the crew safety cannot be guaranteed without its reliable and collision-free separation.

The tests were run on a CTS model in the large trans-sonic wind tunnel T-128 of TsAGI in subsonic mode using a computer-aided rig.

The experiment simulated separation of the parachute compartment hatch cover to various distances within a wide range of angles of attack of the re-entry vehicle. At the same time the aerodynamic forces and torques acting on this element of the model were recorded. The subsequent analysis of the experimental data will make it possible to determine the most efficient and safe modes of jettisoning the cover, said the chief specialist of the department for study of aerothermodynamics of hypersonic aerospace and rocket vehicles at TsAGI Vladimir Plyashechnik.

The obtained set of experimental data will enable RSC Energia specialists to verify and update the analytical methods for determining the behavior of the parachute container cover during its jettisoning from the re-entry vehicle. Thus, the results of the experimental studies done at TsAGI will help in coming up with a sound and reliable design for the structure and operational modes of one of the structural elements of the spacecraft.

Orel is a new-generation reusable crew transportation spacecraft that is being developed by S.P.Korolev RSC Energia. It is designed to take people and cargo beyond the low Earth orbit towards, among other things, the Moon. If need be, a stripped-down version of the spacecraft could be used for missions to space stations in low Earth orbit. Orel will carry a crew of up to four. The spacecraft will be able to stay in free flight for a period of up to 30 days, and stay attached to a space station for a period of up to 1 year.

Zhukovsky TsAGI (Central Aerohydrodynamic Institute, which is a part of the Scientific Research Center Zhukovsky Institute) was founded December 1, 1918. Today TsAGI is the largest state-owned scientific center for aviation and rocket and space industry of the Russian Federation, which successfully solves extremely complex problems in fundamental and applied sciences of aero- and hydrodynamics, aeroacoustics, flight dynamics and structural integrity of flying vehicles, as well as industrial aerodynamics.The institute has unique state-of-the-art experimentation facilities.TsAGI provides state expert reviews for all flying vehicles developed at Russian design bureaus and gives a decisive judgment on whether it is possible and safe to make the first flight.TsAGI takes part in drawing up state programs for development of aviation technology, as well as in the development of flight worthiness standards and governmental regulatory documents.

National Research Center Zhukovsky Institute was established pursuant to the Federal Law No. 326- dated November 4, 2014 to manage and perform scientific research work, to develop new technologies in high-priority areas of aviation technology, to accelerate manufacturing application of scientific research results and to use scientific achievements for the benefit of our national economy. The Center is masde up of Zhukovsky Central Aerohydrodynamic Institute, Baranov Central Institute for Aviation Engine Engineering (TsIAM), State Scientific Research Institute for Aviation Systems (GosNIIAS), Chaplygin Siberian Aviation Research Institute (SibNIA) and Public State Research and Testing Range for Aviation Systems (GkNIPAS).

S.P. Korolev RSC Energia (which is a part of State Corporation ROSCOSMOS) is the leader in the rocket and space industry, and the prime contractor for manned space systems. The Corporation conducts work on the development of unmanned space and rocket systems (launch vehicles and orbital transfer vehicles), and high-technology systems for various non-space applications.
