Linearized Mathematical Models for De Havilland Canada 'Buffalo and Twin Otter' STOL Transports
TRANSPORTATION SYSTEMS CENTER CAMBRIDGE MA
Pagination or Media Count:
Linearized six degree of freedom rigid body aircraft equations of motion are presented in a stability axes system. Values of stability derivatives are estimated for two representative STOL aircraft - the DeHavilland of Canada Buffalo and Twin Otter. These estimates are based on analytical expressions included in the report. The combination of the equations of motion and the estimated stability derivatives provides an aircraft model which is useful for Navigation, Guidance and ATC Studies. Resulting transient responses to control inputs are presented.
