File Description [top]

Dissertation Abstracts Online is a definitive subject, title, and author guide to virtually every American dissertation accepted at an accredited institution since 1861. Selected Masters theses have been included since 1962. In addition, since 1988, the database includes citations for dissertations from 50 British universities that have been collected by and filmed at The British Document Supply Centre. Beginning with DAIC Volume 49, Number 2 (Spring 1988), citations and abstracts from Section C, Worldwide Dissertations (formerly European Dissertations), have been included in the file.

Abstracts are included for doctoral records from July 1980 (Dissertation Abstracts International, Volume 41, Number 1) to the present. Abstracts are included for masters theses from Spring 1988 (Masters Abstracts, Volume 26, Number 1) to the present.

  /AB        This dissertation represents the consideration of the 
     problem of aircraft control failures from a broader, more 
     meaningful viewpoint than with control loop reconfiguration or 
     redesign. The additional considerations involved in making full 
     recoveries from control failures are first categorized. New 
     performance and operating constraints that are best taken into 
     account explicitly are presented, and there is a discussion of 
     the sometimes very important role of explicit post-failure retrim 
     of the aircraft. Because it can be expected that pilots, if 
     unaided, may continue often to be unable to recover aircraft 
     after control failure, these considerations have been cast in the 
     form of knowledge and capabilities that an automatic aid and 
     pilot advisory system should have. Each major element is 
     supported with information from aircraft accident cases and from 
     simulations of post-failure flight of a C-130 aircraft. Because 
     automatic emergency control is seen to be a very significant part 
     of the proposed system, a rule-based expert-type system to find a 
     successful control strategy has been developed for elevator 
     failures on the C-130. This system directs pre-simulation of the 
     control strategy, changing it on the basis of empirical 
     guidelines concerning simple, objective features of the aircraft 
     response to the strategy. As shown in numerous examples, few 
     iterations are required to find successful emergency control. As 
     is discussed, this rule-based approach has no known restrictions 
     with respect to type of aircraft, automatic control also in use, 
     or control failure, as well as length of delay for failure 
     identification. This approach seems to be one that would allow 
     possible use of any remaining control capability, including 
     unusual controls or maneuvering, and of finding the 
     counterintuitive recoveries that, as is shown, are sometimes 
     required. The advisory function of the recovery-aiding system is 
     also described. The issues of pilot interface are discussed, as 
     well as what to calculate to support the advisory during various 
     flight phases. It is believed that the automatic aid and advisory 
     system described, including the rule-based system for finding 
     emergency control, is a good, viable solution to the problem of 
     aircraft control failures.
