The aircraft development embraces the series of numerical experiments and bench tests for models and prototypes. The article deals with the concept of a model experiment and its methodology. We consider an example of design of a compact descent vehicle with inflatable aeroelastic brakes. We describe the brake modules working sequentially in atmospheric entry (supersonic flight) and final breaking in the atmosphere. The model experiment features include the use of CAD/CAE/CAM technology and rapid prototyping technologies for numerical calculation verification according to experimental data for compact models of descent aircrafts. The proposed methodology makes it possible to identify information objects of common information space for cooperation of different specialists such as designers, calculators, technologists and testers. That improves experiment repetition and planning when designing the aircrafts elements.
