A Uav Twin Rocket-propelled Launch Dynamics Modeling And Simulation Studies

Rocket booster launching is a fashion which has highly degree of difficulty and manyfactors considered in UAV launching Simulating a certain UAV launching stage andanalyzing and optimizing launching parameters are carried out by using ADAMS softwarein this dissertation, whose primary studying objects are gas-dynamical characters of UAVand setting parameters of booster rocket and whose targets are flying stability and securityof UAV launching stage, which can provide some references for the whole design of UAVlaunching systems. The mainly works as follows:1. 3D curved face of a certain UAV, solid models of booster rocket and launcher areestablished by using I-DEAS software which defines gas-dynamical characters of UAV.2. Computed simulations of moving and stressing are carried out for UAV inside oflaunching container which is based on system dynamics model established in ADAMSsoftware.3. Kinetic equations of UAV flying in vertical plane and quiet wind field areestablished under the hypotheses ignoring curvature and revolving of the earth, and thenaero dynamical model is established based on initial conditions which are parametersobtained by dynamical analyzing when UAV is away form launcher. Simulation andanalysis are developed for the period in which UAV is away from launcher and then rollbooster separate in Aircraft module belonged to ADAMS software.4. A simulating method, which relatively approaches the practical circumstance, isproposed by analyzing the problem coupled of launching dynamics and flight dynamics.Competed work not only can provide some effective parameter for the UAVlaunching but also propose a new attempt method for the simulation of UAV launching.
