Manoeuvre Point Properties of the AeroIsodinic Wing

Manoeuvre Point Properties of the AeroIsodinic Wing As part of the R.A.E.s critical study of the aeroisoclinic principle of wing design, a detailed examination was made of highspeed aeroelastic effects on manoeuvre point, with special reference to the effect of rearward movement of local aerodynamic centres at supercritical Mach numbers. From the results of calculations, using the method of R.A.E. Report No. Aero. 2320, it is concluded that as regards possible shifts of manoeuvre point, the aeroisoclinic wing is generally superior to the conventional wing. For tailless aircraft, application of the aeroisoclinic principle makes it possible to employ wings of an aspect ratio much larger than is considered practicable with conventional design. Structural design of a flutterfree aeroisoclinic wing entails radical departures from orthodox procedure, and with tailed aircraft it is therefore probably preferable to adapt the design of the tail plane and its attachment, to cope with the destabilizing deformability effects of a conventional wing, than to eradicate such effects at the source by aeroisoclinic design of the wing. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

As part of the R.A.E.s critical study of the aeroisoclinic principle of wing design, a detailed examination was made of highspeed aeroelastic effects on manoeuvre point, with special reference to the effect of rearward movement of local aerodynamic centres at supercritical Mach numbers. From the results of calculations, using the method of R.A.E. Report No. Aero. 2320, it is concluded that as regards possible shifts of manoeuvre point, the aeroisoclinic wing is generally superior to the conventional wing. For tailless aircraft, application of the aeroisoclinic principle makes it possible to employ wings of an aspect ratio much larger than is considered practicable with conventional design. Structural design of a flutterfree aeroisoclinic wing entails radical departures from orthodox procedure, and with tailed aircraft it is therefore probably preferable to adapt the design of the tail plane and its attachment, to cope with the destabilizing deformability effects of a conventional wing, than to eradicate such effects at the source by aeroisoclinic design of the wing.
