The Orbital-Platform Concept for Nonplanar Dynamic Testing (Le Concepte de la Plate-Forme Orbitale Pour les Essais Dynamiques Non-Plan)

Abstract

A new concept is introduced for large-amplitude nonplanar testing at high incidence. The dynamic test apparatus is characterized by an annular, orbital platform on which the model support and secondary drive mechanisms are mounted. The device can be used as a rotary apparatus, while arbitrary epicyclic motions (including fixed-plane, orbital modes) and oscillatory motions superimposed on the coning mode may be generated. The system is inherently very rigid and vibration levels can be kept very low. Aerodynamic interference is also very low as there is no need for bulky support hardware and the test section is circular. Accordingly, the system may be used to assess levels of support interference in conventional rotary tests. Keywords: Nonplanar dynamic tests, Orbital space stations, Aerodynamic testing, Canada.
