A Multi-Diagnostic Approach to Testing V/STOL Craft
§ The interactive aerodynamics of new V/STOL designs require a new approach to ground testing, where multiple properties are measured both on and away from surfaces during continuous changes in test parameters. Using a set of experiments of increasing complexity, a new capability is demonstrated for capturing surface pressure, velocity fields and vortex flow features over a range of test parame...
متن کاملThe Cost of Noise Reduction for Powered - Lift Stol
The direct operating costs and noise impacts of a wide variety of Externally Blown Flap and Augmentor Wing STOL short haul transport aircraft designs were evaluated to study the costs of noise reduction for these types of aircraft. The "two-stream" Augmentor Wing designs were found to be capable of the greatest noise reductions, and to have the lowest direct operating costs at all levels of noi...
متن کاملdesigning and implementing a 3D indoor navigation web application
During the recent years, the need arises for indoor navigation systems for guidance of a client in natural hazards and fire, due to the fact that human settlements have been complicating. This research paper aims to design and implement a visual indoor navigation web application. The designed system processes CityGML data model automatically and then, extracts semantic, topologic and geometric...
متن کاملRobust Gain-Scheduled Control for Planar V/STOL Aircraft with Time-Varying Mass and Moment Parameters
This paper considers a robust gain-scheduled control approach for the planar vertical takeoff aircraft dynamics. The uncertain property of the aircraft mass, moment, and the non-minimum phase parasitic coupling are all addressed by considering their reasonable range in the progress of controller design. An approach of composite control law is performed addressing all the inherent uncertainties ...
متن کاملAdaptive Fusion of Inertial Navigation System and Tracking Radar Data
Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...
