Review ArticleOpen accessModern Propulsions for Aerospace-A ReviewRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.A spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. There are several different methods, each with advantages and disadvantages, spacecraft propulsion being an active area of research. However, most current spacecraft are propelled by forcing a gas exits through the rear of the vehicle at high speed through supersonic nozzle of a rocket engine. All spacecraft … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 12,881 accessesView PDF Cite

Research ArticleOpen accessSomething about the V Engines DesignRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella et al.First time the corresponding author has studied these problems of motors in V, in the framework of some contracts made with the research collective of UPB and "Autobuzul" plant, in years 1980-1986. In the first phase, have been studied the vibrations and noises of an engine in V, their transmissibility from the engine to the chassis and the cab driver … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 31 Dec 2016 · 8,861 accessesView PDF Cite

Research ArticleOpen accessSomething about the Mechanical Moment of InertiaFlorian Ion T. Petrescu, Antonio Apicella, Aversa Raffaella et al.In this study, the relations to determining mass moments of inertia (mechanical) for different mass and mechanical inertia corresponding to geometric shapes, objects and profiles are explored. The formulas for calculating the mass moments of inertia (mechanical) for various bodies (various geometrical forms), to certain major axis indicated (as the axis of calculation) are presented. The total mass M of … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 4 Nov 2016 · 11,376 accessesView PDF Cite
