Abstract

This paperd escribesa n IntegratedV ehicle Modeling Environment for estimating aircraft geometric, inertial, anda erodynamicc haracteristicsa, ndf or interfacingw ith a high fidelity, workstation-basedfl ight simulation architecture. The goals in developing this environment are to aid in the design of next generation intelligent flight control technologiesc, onductr esearchin advanced vehicle interfacec onceptsf or autonomousa nd semiautonomousa pplications,a ndp rovide a value-added capability to the conceptual design and aircraft synthesis process.R esultsa rep resentedfo r threea ircraft by comparinge stimatesg eneratedb y the IntegratedV ehicle Modeling Environment with known characteristicso f each vehicle under consideration. The three aircraft are a mid-sized, twin-engine commercial transport concept, a modifiedF - 15 with moveablec anardsa ttachedt o the’ airframe,a nd a small, single-engine,u ninhabiteda erial vehicle. Estimated physical properties and dynamic characteristicsa re corielatedw ith thosek nown for each aircraft over a large portion of the flight envelope of interest. The results show significant improvement in estimatingv ehicle aeirodynamic haracteristicsu sing an improvedv ortex lattice code,a nd representh e completion of a critical step toward meeting the stated goals for developing ‘this modeling environment.
