Launch process simulation of a ship-borne multiple launch rocket System
Simulation research on the launch process of a ship-borne multiple launch rocket system is studied in this paper. First, the power spectrum density of the ship’s motion is calculated based on ocean wave energy spectrum, and the movement spectrums of the ship’s random motion are calculated. Then, the model of shipborne rocket launcher system is built by virtual prototype technology. The launch p...
متن کاملAcoustic-Mean Flow Interaction in Solid Propellant Rocket Motors
There are several sources for pressure oscillations in solid propellant rocket motors. Oscillatory flow field is one of them. Free shear layers in motor flow field cause vortex shedding. End edges of propellant grains and baffle edge in two-segmented motors are samples of such zones. These vortices move from their forming points and strike the field walls. The kinetic energy of vortices change ...

متن کاملOver-flight Risk Considerations for the Launch of an ELV Rocket to an ISS Inclination
Congress granted the FAA the authority to license commercial launch and reentry operations to ensure protection of public, property, the national security and foreign policy interests of the United States and to encourage, facilitate, and promote U.S. Commercial Space Transportation. To meet this responsibility, the FAA performs safety evaluations of license applications to conduct commercial l...
متن کاملSimulation research on air-burst dispersion of some multiple launch rocket system
Abstract. In order to research the air burst dispersion (ABD) of a new multiple launch rocket system, a simulation method is presented in this paper, which is concentrate on analyzing the influence of various random factors on ABD. First a launch dynamic model is established to simulate the initial disturbance that affected by impact force of gas. Then the influence of combustion-gas flow upon ...
