This paper discusses a new flight test facility at MIT known as the Real-time indoor Autonomous Vehicle test ENvironment (RAVEN) which enables the exploration of aggressive aerobatic flight with relatively low risk. A key feature of this work is that the control algorithms are often the limiting factor because the flight dynamics are highly nonlinear and not well known, and they can change with...

Unconventional aircraft are being studied by the aeronautical engineering community with accelerated interest and effort to improve economic efficiency and to overcome operational and infrastructure-related problems associated to the increasing size of transport airplanes. The objective of the research reported here is to assess the technical feasibility and operational efficiency of a medium s...

The joined-wing is a new concept of the airplane wing. The fore-wing and the aft-wing are joined together in a joined-wing. The range and loiter are longer than those of a conventional wing. The joined-wing can lead to increased aerodynamic performance and reduction of the structural weight. In this research, dynamic response optimization of a joined-wing is carried out by using equivalent stat...

In this paper a combination of Fuzzy Logic Control (FLC) and Model 1 Reference Adaptive Control (MRAC) will be developed to stabilize and control a 2 fixed-wing unmanned aerial vehicle (UAV). The control must be able to direct the 3 airplane towards different waypoints while at the same time maintaining the UAV 4 stable. Also, the control should be transferable to similar UAV models with little...

In this work, we define a parabolic equation on digital spaces and study its properties. The equation can be used in investigation of mechanical, aerodynamic, structural and technological properties of a Moebius strip, which is used as a basic element of a new configuration of an airplane wing. Condition for existence of exact solutions by a matrix method and a method of separation of variables...

The time-optimal trajectory for an airplane from some starting point to some final point is studied by many authors. Here, we consider the extension of robot planer motion of Dubins model in three dimensional spaces. In this model, the system has independent bounded control over both the altitude velocity and the turning rate of airplane movement in a non-obstacle space. Here, in this paper a g...

Abstract—In this work a dynamic model of a new quadrotor aerial vehicle that is equipped with a tilt-wing mechanism is presented. The vehicle has the capabilities of vertical take-off/landing (VTOL) like a helicopter and flying horizontal like an airplane. Dynamic model of the vehicle is derived both for vertical and horizontal flight modes using Newton-Euler formulation. An LQR controller for ...
