Application of dynamical systems theory to the high angle of attack dynamics of the F-14 [PDF]

open access: yes, 1990
Dynamical systems theory has been used to study the nonlinear dynamics of the F-14. An eight degree of freedom model that does not include the control system present in operational F-14's has been analyzed.

Comparison of upwind and downwind rotor operations of the DOE/NASA 100-kW Mod-O wind turbine [PDF]

open access: yes
Three aspects of the test results are compared: rotor blade bending loads, rotor teeter response, and nacelle yaw moments. As a result of the tests, it is shown that while mean flatwise bending moments were unaffected by the placement of the rotor ...

Lateral ride quality of the B-1 aircraft subjected to a reduction of lateral static stability [PDF]

open access: yes
A method to evaluate the lateral ride quality of a B-1 aircraft subjected to a reduction in lateral static stability is developed. Ride quality is then found for three different relaxed static stability configurations which are augmented by yaw rate ...
