A Stol Airworthiness Investigation Using A Simulation Of A Deflected Slipstream Transport Volume 3 Breguet 941s Simulation Model

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.

A simulator study of STOL airworthiness criteria was conducted using a model of an augmentor wing transport. This study covered the approach, flare and landing, go-around, and takeoff phases of flight. The two volumes of this report document the results of that investigation. Volume One summarizes the results and discusses possible implications with regard to airworthiness criteria. The results provide a data base for future STOL airworthiness requirements and a preliminary indication of potential problem areas. The results are also compared to the results from an earlier simulation of the Breguet 941S. Where possible, airworthiness criteria are proposed for consideration.

A simulator study of STOL airworthiness criteria for approach and landing was conducted using a series of different aircraft models. These models were selected to isolate a single parameter or characteristic for evaluation. Specific areas included in the study were: an evaluation of speed margins, a flight path margin evaluation, a study of flare and landing technique, the effects of touchdown zone constraints, an evaluation of two different turbulence models, an investigation of flight path/airspeed cross coupling, and a study of the effects of short-term flight path response. This report contains a detailed description of the simulation and the data obtained. These data include performance measures, pilot commentary, and pilot ratings.
