OPTIMIZATION OF COMMERCIAL TRANSPORT AIRPLANE STOPPING SYSTEMS 720872
The role of the aircraft manufacturer in the design, integration, and optimization of commercial transport airplane stopping systems is discussed. Specific emphasis is placed on: system design considerations, configurations, and features; laboratory and flight testing; typical problems encountered; and future basic data requirements. Advancements in stopping system simulation techniques and antiskid control systems in recent years have allowed large improvements in stopping system efficiency. Future improvements are dependent on obtaining basic data on tire and brake dynamic characteristics for use in simulation studies to control and improve the combined brake and tire frequency response phase lag. It is anticipated that new rational landing rules being developed by the FAA must account for and include the effect of the engine thrust reversing system on stopping distances. The design, development, certification, and operation of airplanes with integrated air brake, wheel brake, and thrust reversing systems will further emphasize optimization of the total airplane stopping system.
