we present experimental results obtained by a phase-shifting interferometer employing polarization capable of retrieve directional derivatives in x-direction (lateral shear). the system was adapted to obtain radial derivative (radial shear) and implemented with a cyclic interferometer with phase grid to ...
The locally linearized longitudinal and lateral-directional aerodynamic stability and control derivatives for the X-29A aircraft were calculated for altitudes ranging from sea level to 50,000 ft, Mach numbers from 0.2 to 1.5, and angles of attack from -5 deg to 25 deg. Several other parameters ...
An investigation of the lateral-directional flying qualities of a tandem-rotor helicopter in forward flight was undertaken to determine desirable goals for helicopter lateral-directional flying qualities and possible methods of achieving these goals in the tandem-rotor helicopter. Comparison between direction...
An approach for designing inputs to identify stability and control derivatives from flight test data is presented. This approach is based on finding inputs which provide the maximum possible accuracy of derivative estimates. Two techniqu... Narendra Gupta,W.Earl Hall Jr 被引量: 22发表: 1975年 ...
