FIELD: rocket equipment; astronautics.
SUBSTANCE: invention relates to aerospace engineering. Disclosed heat-resistant coating of aircraft body comprises a belt wound on hull on a spiral. Belt is made out of reinforcement fibres, is impregnated with binder and its surface is located at an angle to surface of body. Belt is arranged with variable thickness of heat shielding coating with angle of inclination to surface of body in range from 5 to 90 degrees. In gaps formed between layers of belt, there is an additional belt; reinforcing fibres in additional belt are shifted relative to reinforcing fibre of belt by an angle from 5 to 80 degrees.
EFFECT: reduced aircraft weight and high-quality improvement of characteristics of heat protection due to increased thermal erosion resistance combined with improvement of its heat-insulating properties.
