    The complete model flutter tests made on the B were carried out in a low-speed wind tunnel, and the results were then adjusted for estimated Mach number effects. Later techniques developed by NACA and NASA allow flutter tests of complete airplane [ ] models to be made at high subsonic and transonic Mach numbers in a wind tunnel. used as standard for checking and controlling the new wind tunnel installations. The model has adequate internal space for setting up three component wind tunnel balance with diameter of 15mm. Airfoils of the wing and airfoils of the horizontal and vertical tails are symmetrical with maximum thickness of % at the % of the by: 2.

      LS(1) indicated the first series of low-speed airfoils, the next two digits designated the airfoil design lift coefficient in tenths, and the final two digits gave the airfoil thickness in percent chord. Thus, the GA(W)-1 airfoil became LS(1) and the GA(W)-2 airfoil became LS(1) It is our intention for Summary of Low-Speed Airfoil Data – Volume 5 to follow closely the format of the previous volumes making the current installment easy to navigate for those familiar with the series. As before, Chapter 1 discusses the scope of the current tests and briefly describes the airfoils and configurations tested.
