29 giu 2024 · An air film typically consists of air molecules. It forms a thin layer of air between two surfaces, such as between a solid object and a liquid or another solid.
2 giorni fa · Infra-red passive homing (AM-modulated reticle seeker head with uncooled PbS detector element), proportional navigation logic. The 9K32 Strela-2 ( Russian: Cтрела, lit. 'Arrow'; NATO reporting name SA-7 Grail) is a light-weight, shoulder-fired, surface-to-air missile or MANPADS system.
1 lug 2024 · Prefilming airblast atomisers are commonly used in gas turbine combustion system fuel injectors. As the film propagates across the prefilmer it interacts with the high velocity gas stream above it. In this paper a numerical investigation into this interaction is presented.

1 lug 2024 · Blade tip leakage is responsible for reducing the aerodynamic performance and increasing the thermal load. In order to obtain better cooling efficiency, the thermodynamic performance of different film hole arrangements and blowing ratios have been compared and analyzed in a cavity tip structure.
