Abstract:

Because of the interest in swept-back wings for high-speed airplanes an analysis has been made of readily available data on the longitudinal stability characteristics of swept-back wings at low speeds. The analysis indicated that the shape of the pitching-moment curve near the stall for swept-back wings is greatly dependent upon the aspect ratio. A chart has been prepared relating aspect ratio and sweepback that indicates the combinations of aspect ratio and sweepback alone. The effect of the addition of a horizontal tail behind a swept-back wing may be destabilizing and requires further investigation.
