LIFT AND PROPULSION INSTALLATION OF AIR-CUSHION TRANSPORT VEHICLE Abstract of the Disclosure Disclosure is made of a lift and propulsion installa- tion of an air-cushion transport vehicle wherein an axial fan with a wheel thereof is installed in the entrance por- tion of an annular duct. Arranged at the exit of the annular duct are a diffuser and a box pneumatically associat- ed with the axial fan, and disposed internally in the annular duct is a cylindrical splitter dividing the annular duct into an external passage and an internal passage. The external annular passage is communicated through the box with the space of an air-cushion, while the internal annular passage is communicated with a thrust nozzle pro- vided at its exit with a reverse-steering device having pivoted rudders and reversing blades installed after the fan wheel. The fan wheel has two rows of blades and each blade of the first row is provided at its peripheral portion with a sec- tion having a wing-like curved profile disposed before the entrance into the external annular passage, whereas its lower portion has a symmetrical flat profile arranged before the entrance into the internal annular passage, the blades of the first row being fixedly secured on a hub of the fan wheel and the blades of the second row being installed on the same hub before the entrance into the internal annular passage and adapted to be turned each around its radial axis. Straightening blades are installed at least in one of the annular passages after the working blades. The invention may suitably be used in the development of air-cushion transport vehicles, for example air-cushion craft, self-propelled transport platforms and like appara- tuses.
