A wind tunnel investigation was performed to study the flow field over a 70° swept sharped edge delta wing model at high angles of attack. The experiments were conducted in the subsonic wind tunnel at the Department of Mechanical Engineering, Sharif University of Technology. Velocity profiles have been measured using a special pitot tube and hot wire anemometer at angles of attacks of 10 to 35 ...

Aircraft on approach in high-drag and high-lift configuration create unsteady flow structures which inherently generate noise. For devices such as flaps, spoilers and the undercarriage there is a strong correlation between overall noise and drag such that, in the quest for quieter aircraft, one challenge is to generate drag at low noise levels. This paper presents a rigorous aero-acoustic asses...

In the pursuit of pushing active character control into games, we have deployed a generalized physics-based locomotion control scheme to multiple simulation platforms, including ODE, PhysX, Bullet, and Vortex. We first overview the main characteristics of these physics engines. Then we illustrate the major steps of integrating active character controllers with physics SDKs, together with necess...

In this paper, the authors proposed a novel reactive strategy to solve a unknown object local manipulation problem with an multifingered robot hand. In this method, the micro manipulation assumption is proposed and the object can be manipulated within the robot hand workspace without the active and explicit controlling about the rolling and sliding of the fingertips on the object. A 6 D.O.F rea...

The paper is part of the research aimed at determining if vortex flow pancake (VFP) hybrid rocket engine feasible as green in-space chemical propulsion. objective this study to test an N2O/HDPE VFP ignited with N2O/C3H8 torch igniter. N2O used in self-pressurizing mode, which results two-phase and varying inlet conditions, thus better simulating real behavior. begins characterizing igniter, fol...

Rotor tip-clearance induced noise, both in the form of rotor self noise and rotor-stator interaction noise, constitutes a significant component of total fan noise. Innovative yet cost effective techniques to suppress rotor-generated noise are, therefore, of foremost importance for improving the noise signature of turbofan engines. To that end, the feasibility of a passive porous treatment strat...
