NASA-CR-3295: Selected advanced aerodynamics and active controls technology concepts development on a derivative B-747 aircraft
Abstract: Analytical design and wind tunnel test evaluations covering the feasibility of applying wing tip extensions, winglets, and active control wing had alleviation to the model B747 are described. Aerodynamic improvement offered ...
NASA-TT-F-734: Flight of aircraft with partial and unbalanced thrust
Abstract: The problem of aircraft operation under conditions of unbalanced thrust following the failure of an engine on a multi-engine aircraft is examined. The dynamics of the divergent motion of the aircraft immediately after ...
NASA-CR-2200: Maximum likelihood identification and optimal input design for identifying aircraft stability and control derivatives
Abstract: A new method of extracting aircraft stability and control derivatives from flight test data is developed based on the maximum likelihood cirterion. It is shown that this new method is capable of processing data from both ...
