The criteria, design, installation and flight calibration of a variable drag system are discussed. The system allows for variable L/D characteristics in the variable stability T-33 airplane.

With this system in the special T-33, the airplane will be used to investigate the interactions between handling qualities and many drag characteristics including very low L/D and shapes of L/D curve for high L/D ratios.
