The use of the estímation-before-modellíng (EBM) two step identification procedure for the determination of aircraft aerodynamic derivatives from flight test data is analysed and illustrated. In the first step of the ...

The robust loop-shaping control methodology is applied in the flight control system design of the Cranfield A3 Observer unmanned, unstable, catapult launched air vehicle. Detailed linear models for the full operational ...

This work is concerned with the design of a pitch-rate-command-attitude-hold command and stability augmentation system in order that the augmented aircraft meets the Gibson dropback criterion, the Gibson phase-rate criterion ...

lt is the author's contention that a brake control system incorporating the following two features is suitable for high-performance, robust and adaptive anti-skid control. 1. Switching on wheel acceleration with ...

A mobile experimental test facility has been developed to carry out the aerodynamic evaluation of hang glider wings normally performed in a wind tunnel. Longitudinal aerodynamic data obtained using this facility ...

The challenge of integrating the UAV fleet into the carrier landing operational structure with respect to navigation and control strategies is addressed. A simulation model was developed which includes an aircraft model, ...

Fly-by-wire flight control systems are becoming more common in both civil and military aircraft. These systems give many benefits, but also present a new set of problems due to their increased complexity compared to ...

In order to construct a flight dynamics computer simulation model of airship flight with a high degree of fidelity in the aerodynamic modelling, extensive wind tunnel testing was carried out. This was aimed at, first ...

Recent advances in composite structures and active control systems have made the concept of a forward swept wing aircraft a viable alternative to the more conventional configurations. This thesis encompasses some of the ...
