| Basic principles of designing of impulse hydrodynamic tunnels (IHDT) are stated. A comparison of parameters of existent HDT of continuous opetation with parameters of the impulse tunnels is performed. It is shown that in exploitation and building the IHDT have power and economic consumptions lower on 1-2 orders at identical technical parameters. Systems of IHDT operating according to the hydropressure and pneumohyrdropressure schemes are considered. The flow regimes in a working part are analysed, the phenomena of hydroimpact and cooling of gas at expansion are estimated when the compressed air is used for increasing the flow velocity. Methods of calculating the IHDT is given. |
