THRUST VARIATION [2 records]

CONT

The tail rotor assembly is made up of a mast, hub, two scissors assemblies, four pitch control rods, slider, spider, four dampers, four blades and control(extension) rod.... The variation of the collective pitch of the blades for the thrust control is possible due to a translational movement(inwards and outwards) of the four pitch control rods. The spider-slider assembly rotates together with the hub-blades system and translates together with the extension rod, which is moved by a servoactuator system. The two scissors assemblies keep the spider-slider assembly rotating together with the hub. The dampers have the function of damping the lag movement.

PHR

Universal joint spider.

Systems Analysis of a Future Semi-Reusable Launcher, Based on a High Thrust Bleed Cycle Rocket Engine. In this paper a high thrust, cryogenic bleed cycle engine, to be used for propulsion of future reusable booster stages(liquid fly back boosters), of an expendable heavy lift launcher, is analyzed. The system configuration remains unchanged, in terms of total available fuel and the number of engines, hereas the variation of the engine parameters result in a change of total system mass and payload capacity. Different arrangements of bleed cycles are being analyzed, and compared with each other. The paper describes a simplified heat transfer model, used in the analysis of the suggested cycles. The thrust chamber design is discussed and a preliminary design of the booster vehicle, including a trajectory analysis, is presented.

CONT

Cinq navettes furent construites [...] pour remplacer Challenger [...] Au départ ce devait être un lanceur récupérable. Mais les coûts exorbitants obligèrent les responsables à le transformer en un lanceur semi-récupérable. Le gros réservoir est devenu un élément ordinaire. Seuls l'orbiteur et les propulseurs auxiliaires sont récupérés.
