A survey of available wind shear data was conducted and the results were related to current design practices for vertically rising missiles. The responses of several different kinds of vehicles were obtained by means of a 6-dimensional trajectory computer program. The maximum wind velocity and the integrated area under the wind profile up to the critical altitude at which the maximum wind velocity occurs were found to be critical parameters. A design procedure was developed for the construction of a design response diagram. This relates the vehicle response to the maximum wind velocity, its probability distribution, and the probability distribution of the integrated area. Since no statistics in the integrated area are available, a method of estimation was also developed, involving the use of four design wind profiles. These design diagrams are useful during all phases of design, as well as pre-launch checkout. The proposed procedure has a high degree of flexibility which permits optimization of the design of a missile system. As a result the launch probability can be optimized with respect to the mission of the vehicle and the structural weight traded off against payload capability or flight performance.
