Abstract:

For aircraft /store compatibility, a comprehensive software system requested by the Air Force for rapid assessment of flutter and ejection loads (RAFEL) poses challenging requirements. With ZAERO aeroelastic software as a base, ZONA can establish a RAFELsystem satisfying all AF's requirements. Specifically, ZONA will develop RAFEL in Phase I with: a) solution accuracy with flutter solution robustness via ZONA's g-method, high-fidelity ZONA aerodynamic wing-body modeling, extended flutter/unsteadyaerodynamic range covering subsonic/transonic and supersonic Mach numbers; b) computation efficiency for massive store/aircraft combinations; and c) rapid selection of critical cases of flutter, ASE instability, LCO and ejection loads. RAFEL programarchitecture contains three subsystems: i) unified aerodynamic influence coefficients (UAIC) matrix system of ZAERO to substantially reduce repetitive computing effort; ii) massive store management (MSM) system for effective data management of UAICassembly; iii) a data mining system for rapid screening MSM data and selection of all critical cases. Selected test cases for RAFEL validation include three distinctive F-16/store cases in transonic flight. ZONA is committed to work closely with AF inPhase II to achieve a fully integrated RAFEL system in a distributed computing environment with added capability in flutter-mode tracking, optimum store-release scheduling, minimized ejection loads and a GUI system.ZONA envisions that the fully integratedRAFEL system will be a unique product for aircraft compatibility analysis surpassing all existing engineering tools.(1) ZONA plans to package RAFEL system for commercialization with AF/CRADA.(2) ZONA will market RAFEL in parallel to ZAERO aeroelastic software system.(3) Potential customers include DoD, Aerospace/Defense industry and private sectors.(4) RAFEL can apply to military/commercial/ GA aircraft and future fighters/UCAVs
