Research ArticleOpen accessHome at AirbusRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Airbus Commercial aircraft, known as Airbus, is a European aeronautics manufacturer with headquarters in Blagnac, in the suburbs of Toulouse, France. The company, which is 100% -owned by the industrial group of the same name, manufactures more than half of the airliners produced in the world and is Boeing's main competitor. Airbus was founded as a consortium by European manufacturers … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 2 · 5 Jul 2017 · 9,564 accessesView PDF Cite

Research ArticleOpen accessElectron DimensionsRelly Victoria Virgil Petrescu, Raffaella Aversa, Shuhui Li et al.In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 7,576 accessesView PDF Cite

Research ArticleOpen accessTesting by Non-Destructive ControlRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.This paper describes an application of industrial robots that gain ground mainly in the aerospace industry. It is a TTT manipulator whose task is to automatically position the end-effector, in this case a complex sensor system and a eddy-current probe in the position set by the software application for testing by non-destructive ultrasound control of tickets and bars of titanium, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,698 accessesView PDF Cite

Research ArticleOpen accessDynamics of Mechanisms with Cams Illustrated in the Classical DistributionRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The paper presents an original method to determine the general dynamics of rotating cam and lifting, customized to flat-plate mechanism. First, the dynamic cinematic is presented. Then the Lagrange equation is resolved and with an original dynamic model with a degree of freedom with variable internal damping the dynamic analysis of two models is then made. The mechanisms presented, scientifically … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 8,491 accessesView PDF Cite

Review ArticleOpen accessHistory of Aviation-A Short ReviewRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The man has always wanted to be able to fly. The dream or although it has achieved, has not been reached yet fully. The fuse of the flight today is much higher than in the past, but is not yet complete. Although they have carried out the steps in the increase of the safety of a ship in flight, there … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 22 May 2017 · 16,578 accessesView PDF Cite

Research ArticleOpen accessModern Propulsions for Aerospace-Part IIRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Speaking about a new engine ionic means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that accelerates the positive ions through a potential difference) is approximately ten times more efficient … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 8,118 accessesView PDF Cite
