An investigation was made in the Langley gust tunnel of a 60 degree sweptback-wing model to determine the effect of a large angle of sweep on gust loads. On the basis of the results, a simplified method of analysis, which uses a slope of the lift curve derived by the cosine law and which uses strip theory to estimate the penetration effect, appears to be applicable to the prediction of gust loads on wings swept as much as 60 degrees.
