This paper investigates the nonlinear dynamics of a vehicle with two flexible flapping wings. The body dynamics and the wings’ deformation are monolithically grouped into a single system of equations, with aerodynamics accounted for by a quasi-steady blade element method. A periodic shooting method is then used to locate closed orbits of this non-autonomous system, and Floquet multipliers asses...

Diffusers and the floor ahead of them create majority downforce a vehicle creates. Outside motorsports, diffuser is relatively unused, although its interaction with ground consistent field study owing to aerodynamic benefits. The flow behavior governed by three fluid-mechanical mechanisms: interaction, underbody upsweep, upsweep. In addition, four different regimes appear when varying ride heig...

A mid-fidelity aerodynamic solver based on the vortex particle method for wake modeling, DUST, is coupled through partitioned multi-physics coupling library preCICE to a multibody dynamics code, MBDyn, improve accuracy of aeroelastic numerical analysis performed rotary-wing vehicles. In this paper, tool firstly validated by solving simple fixed-wing and problems from open literature. The transi...

Computational Fluid Dynamics has emerged as one of the major investigative tools for aerodynamics and thermal analyses today’s road vehicle design processes. This work presents a new heat exchanger layout that could support transition from to electrical propulsion an existing motor vehicle. A procedure is established develop assess prototype. The aerodynamic performance electric equipped with a...

An independent assessment of the Advanced Reusable Transportation System (ARTS) has been conducted. The ARTS concept is an all-rocket, fully reusable launch vehicle utilizing electromagnetic launch assist. ARTS is fitted with a dual-fuel main propulsion system utilizing flight proven Space Shuttle Main Engines and RD-180s. Nominally, the vehicle is intended to operate without a crew using auton...

Micro aerial vehicles have been the subject of continued interest and development over the last several years. The majority of current vehicle concepts rely on rigid f ixed wings or rotors. An alternate design based on an aeroelastic membrane wing has also been developed that exhibits desired characteristics in f l ight test demonstrations, competition, and in prior aerodynamics studies. This p...
