TsAGI tests reusable rocket system
14 August 2013
TsAGI specialists have completed the latest stage of tests on the model of a reusable rocket system. The tests were carried out in TsAGI’s T-103 subsonic wind tunnel on behalf of the Khrunichev State Research and Production Space Centre.
The research programme into the landing characteristics of the winged unit of the reusable rocket system included more than 40 launches and aimed to study its aerodynamic characteristics, controllability, stability and airflow visualisation.
Earlier, in spring this year, the reusable rocket system was tested for airflow visualisation and the distribution of heat flows. The experiments were carried out in the UT-1M shock tunnel (at M=6) and in the T-117 supersonic tunnel (M=7.5).
“By the first stages of research we had received a lot of valuable results. A number of characteristics contained in the calculations were confirmed. But at the same time new information was also received, which needs to be processed and tested further on improved models and within a wide range of experimental parameters. The high heat flows on the centre section of the wing were a surprise for us — this will definitely result in changes in the structure of the apparatus. Moreover, it turned out that in the current format the reusable rocket would be unstable on its course. The data received is the objective information for which the testing was carried out. It is from these nuances that we receive new fodder for our scientific research, to create the form of the aircraft and fine-tune its structure,” Sergei Drozdov, director of the TsAGI high-speed aircraft thermo-aerodynamics department, said.
The next stage of aerodynamic tests on the model reusable rocket system is planned for September and October 2013 and will take place in the supersonic T-116 wind tunnel and the T-128 trans-sonic tunnel.
