Popis: During the preparation of the Soyuz spaceship for the joint mission with the Apollo spaceship, an investigation was made on a model of the thermal and mechanical effect of the exhaust jets of the Apollo guiding system on Soyuz [1]. The experiments on the model revealed a complicated structure of the gas flow field, in which there were shock waves and rarefaction zones. The experimental values of the heat fluxes were converted to the conditions of actual flight by a method based on dependences for calculating the thermal effect of a supersonic gas jet on bodies of a simple form. Calorimeters of a cylindrical form set up on the spacecraft made it possible to compare the heat fluxes measured during the joint mission with those calculated by this method. In the present paper, the method of converting the experimental model values of the heat fluxes to the actual mission conditions is explained, the construction of the calorimeters and the conditions under which the heat fluxes from the Apollo exhausts were measured are described, and the measured values of the heat fluxes are compared with the values calculated by this method.
