ROCKET BEARER LAUNCHER WITH DEGENERATED SPECTRUM OF MECHANICAL OSCILLATION EMISSION (VARIANTS), COHERENT WITH SUCH DEVICE LAUNCH TECHNIQUE OF ROCKET BEARER AND PREPARATION METHOD TO FULFILMENT OF LATER ONE Russian patent published in 2008 - IPC F41F3/04 

FIELD: transportation.

SUBSTANCE: group of inventions relates to the rocket technique field, in particular to launching ramps (LR) for rocket bearers launching (RB). Elements of LR working surfaces, interrelating while launching with currents of combustion materials (CCM) of engine unit (EU) (gas vents, pan, blast deflector, entry, checker, located in entry and under it), are made with covering, which consists of fragments made of materials, different in sound speed in them, or composed of structural components set, made of materials differ in sound speed in them or in immediate proximity to working surfaces of LR elements with fragments made of materials different in sound speed in them. Stated fragments, constructive elements or insertions can be located irregularly, or fragments, constructive elements and insertions, made of materials with similar sound speed, are located centered, or fragments, constructive elements or insertions are made of materials with different sound speed are interchange each other. After EU launching one supplies in CCM fluid flows for breakdown of supersonic CCM flow structure at the level of first wave structure. While launching of RB at the plate CCM is surrounded with gas-vapor cloud. Besides, one defines configurations of working surfaces of LR details with the usage of LR and RB models. For modeling details are made in particular of the demolishing, or not elastic deforming material, or material, melting under CCM impact.

EFFECT: decreasing of integral control action of oscillations on rocket bearers and launching ramps.
