Pneumatic transport is one of the most progressive means of mechanization and automation of loose goods transportation. It is used in aluminium, chemical, food, textile, construction and other industries. However, wide use of pneumatic transport is limited by the incomplete information on this subject. In this article provides a description of the design of useful models of the suction intake device пневмотранспортной installation. A useful model was developed with the participation of the author of the staff of the Department of transport and technological machines architectural-building University. The author has developed stages of the suction intake unit and carried out theoretical and experimental research on each step to achieve the most effective operation of the device. In view of the fact that for the main parameters of the suction intake devices of the theory of destroying the fabric of a flooded the air flow is not developed to a sufficient degree, the author has studied the process of propagation and interaction of flooded jet with the surface. The article systematized and presents the results of experimental research on the interaction of flooded jets of air sealing with building materials of different kinds. The author determined the optimal parameters of the process of packed loosening material jets of compressed air at the fence material suction fence device.

Technological processes such as forging, die forging, pile driving, etc., are realized as a result of a collision between two bodies. The bodies’ rebound after the collision takes place due to the use of part of the energy of the hit for their elastic deformation. The paper presents results from an experimental research on the possibilities of the decrease of rebound, by the use of an additional force during the hit. A laboratory test-stand is described in which an additional force is created by the use of a cold rocket engine, working with compressed air.

Abstract This article presents the results of an initial design study for a lean fully premixed (LFP) injector for commercial jet engine. The operating point considered is that of an high overall pressure ratio, small core engine at take-off condition. To perform this feasibility study, multiple relevant constraints are taken into account. The three-unit fully premixed injector has been designed by utilizing numerical simulations. The first unit of the injector is intended to perform complete fuel vaporization through heat transfer from the compressed air to the liquid fuel via a compact onboard heat exchanger. The second unit is designed to ensure premixing of the fully evaporated fuel and the air. Finally, the third unit ensures additional premixing and stability of the premixed swirling flame. The autoignition challenge associated with the design of the LFP injector is discussed in this article. The computational modeling approach that was used to design the units of the LFP injector is presented.
