Gasodynamic processes in the vent of the launch complex with small depth for the space small-lift rockets

At present the consumer interest to the launch of small and very-small satellites rises. For their insertion the space small-lift rockets are used. It is expedient to create special small launchers for the launch of such rockets. The authors have developed a scheme of such a launcher, a technique and a calculation program for nonstationary jet streams at launch taking into account the work of water supply systems in which the experimental results obtained for physical analogues and full-scale launching of space rockets are taken into consideration. In the process of calculation the parameters of the two-phase gas-droplet flow are determined, the values of force and heat loads on the elements of launcher and the rocket are found. Computationally intensive investigations show that one can create an operating launcher of minimum size with a short distance from the nozzle section to the jet deflector only when using two levels of water supply and nonrecoverable replaceable elements established at the vertex of jet deflector...
