Similarity Requirements for Flutter and Other Aeroelastic Models in a Cryogenic Wind Tunnel.

Abstract

A consideration of the requirements for aeroelastic similarity shows the low working temperature of a cryogenic tunnel and an ability to vary temperature both have potential advantages in regard to the choice of suitable stiffness and density scales for an aeroelastic model. The advantages are incidental to the main purpose of a cryogenic tunnel, which is to achieve high Reynolds numbers. (Author)
