The research presented in this paper focuses on the effects of structural failures on the safe flight envelope of an aircraft, which is the set of all the states in which safe maneuver of the aircraft can be assured. Nonlinear reachability analysis based on an optimal control formulation is performed to estimate the safe flight envelope using actua...
A safe conversion of tiltrotor from helicopter mode to airplane mode is ensured through maneuvering within the conversion corridor, a constrained region in the airspeed versus nacelle angle graph. This paper presents preliminary work in the development of an automatic conversion maneuver. A high order quasi-Linear Parameter Varying model is develop...
The research presented in this paper focuses on the development of a quasi-Linear Parameter Varying (qLPV) model for the XV-15 tiltrotor aircraft. The specific category of qLPV modeling technique, known as the model stitching technique, is employed to model the time-varying dynamics of XV-15 tiltrotor aircraft over the entire flight envelope. In th...
Tiltrotors can transform from helicopter configuration to a fixed wing airplane configuration. This allows them to have a broader flight envelope. The dynamics of tiltrotors change with flight condition and aircraft configuration. Therefore, a model stitching technique based on quasi-Linear Parameter Varying (qLPV) framework is employed to develop...
The accident rate of rotorcraft has improved signicantly over the years but at a slow pace, and in any case the number of accidents per ight hours is one or two orders of magnitude higher than that of commercial aircraft, a consideration that could be reasonably related to the inherent higher risk associate with rotor-craft operations. This represe...
This paper presents a novel design of a three-degrees-of-freedom parallel manipulator. This manipulator has a crank arm type actuator instead of linear actuator, which is moved by means of servo motors. It has two degrees of orientation (Pitch and Roll) and one degree of translatory motion (Heave). Design is based on crank arm type actuator which c...

Tiltrotors can operate over a broad flight envelope. The ability to hover like a helicopter and at the same time to fly at relatively high cruise speeds and range like a fixed wing aircraft make them an effective point-to-point fast means of transportation. Their multi-role capability not only make them ideal for urban air mobility but also for energy & medical services and search & rescue missions.
Control strategies dramatically change with flight conditions and aircraft configurations. Moreover, the multi-role capability with large flight envelope pose various technical challenges in designing an aircraft to perform adequately over a wide range of aircraft configurations. These technical challenges include Pilot Induced Oscillations (PIO) and Pilot Assisted Oscillations (PAO), structural loads and high workload specially during conversion maneuvers.
The aim of this project is to develop a high order flight dynamics model that can be used in real time with pilot-in-loop simulations and to design novel nonlinear control allocation techniques for tiltrotor aircraft. The goal is to address the technical challenges associated with tiltrotors at a conceptual design phase. Thereby, improving the overall safety and control of the tiltorotor aircraft.
