Tests of the model of the re-entery vehicle of the piloted transport vehicle (PTK) «Federation» on hypersonic flight modes were completed in TsAGI. This is reported by Roskosmos on 9 July.
«The data obtained will make it possible to find out how the temperature is distributed over the surface of the re-entry vehicle of the prospective transport vehicle in the descent section and to clarify the necessary thickness of the heat shield,» the specialists explained.
Scientists also have to determine the aerodynamic characteristics of the head unit of the emergency rescue system and the space head in the space rocket. Another important task for experts is to obtain data on the stability and controllability of objects, the effect of heat, and then analyze the information obtained.
It should be noted that the research is carried out in the wind tunnels of TsAGI. To date, they are recognized as the largest in Russia. Tests should be completed in 2018-2019.
