At high speed, the friction between the air mass and the rocket surface causes a local heating of over 1000 Celsius degrees. For the heat protection of the rocket, on its outside surface thermal shields are installed. Studying the Coanda effect, the fluid flow on solids surface, respectively, the author Ioan Rusu has discovered by simply researches that the Coanda effect could be /extended also to the fluid flow on discontinuous solids, namely, on solids provided with orifices. This phenomenon was named by the author, the expanded Coanda effect. Starting with this discovery, the author has invented a thermal shield, registered at The State Office for inventions and Trademarks OSIM, deposit F 2010 0153 This thermal shield: is built as a covering rocket sheet with many orifices installed with a minimum space from the rocket body takes over the heat fluid generated by the frontal part of the rocket and avoids the direct contact between the heat fluid and the rocket body ensures the evacuation of the infrared radiation, generated by the heat fluid flowing over the shield because of the extended Coanda effect by reflection from the rocket body surface.
