Antithermal Shield for Rockets
At high speed, the friction of air mass with the rocket surface produce local heating more than 1000 0C. For heat protection of rocket, on their outside surface are install antithermal shields.
Studing Coanda effect, respectively, the fluid flow on solids surface, the author Ioan Rusu discover by simply researches that the Coanda effect could be expanded also for the fluid flow on discontinuous solids, respectively, on solids with orifices. This phenomenon was named by the author, the expanded Coanda effect.
Start with this discovery, the author Ioan Rusu invent an antithermal shield, registered at Romanian Patent Office, OSIM, deposit F 2010 0153
This antithermal shield:
- is built as a covering rocket sheet with many orifices install with a minimum space from the rocket body
- take over the heat fluid generate by the frontal part of rocket and avoid the direct contact of heat fluid with the body of the rocket
- assure the evacuation of infrared radiation, generate by the heat fluid who flow on shield by expanded Coanda effect by reflection from rocket body surface
