Development of an Off-line 6-DOF Simulation Program for Store Separation Analysis

Abstract: Off-line 6-DOF simulation program for store separation analysis has been developed. The developed program enables to predict a trajectory of a store from the database which was constructed by wind tunnel testing or CFD analysis. The flow angle method was applied to the program for predicting aerodynamic coefficients from the database and the ejector forces and constraints were enabled to incorporate the equations of motion for computing the trajectory. Using the program, the trajectories were calculated and th… Show more

“…The interference flow field is constructed with CFD (Computational Fluid Dynamics) analysis of the EAD under the influence of the target. The detailed analysis method can be found in [7]. The trajectories of the EAD depend on the scenario of the release: time of separation, target maneuver, ejector force and so on.…”

“…플랫폼으로부터 사출된 이탈방사 체의 궤적 및 자세각은 플랫폼 기동에 의존하며, 이를 정 확히 예측하는 것은 최종 시뮬레이션 결과에 매우 중요 하다. 본 논문에서는 플랫폼의 기동 시나리오에 따른 6자 유도 방정식 [3] 을 풀어 이탈방사체의 궤적을 정확히 해석 한다. 또한, 레이다의 시 영역 수신 신호를 비행체의 2D 편광계(polarimetric) 레이다 시그너쳐 및 이탈방사체의 안 테나 방사패턴, 안테나 이득, 내부 증폭 이득 등 RF 성능 을 고려하여 Friis 전송 방정식을 기반으로 계산한다 [2] .…”
