Preliminary design work, performance and weight studies, and calculation reviews of various configurations which have been in work since goahead on this program have now been reduced to designs for all systems and components. The engineering effort aimed at a Design Freeze in the month of May has been met, with the exception of minor studies to improve the longitudinal and directional stability as a result of the 16 scale wind tunnel testing. The wind tunnel program, design, fabrication and test is being revised to reflect necessary redesigns as a result of the 16 scale model test data. The transmission systems gearboxes and shafting have been reviewed and the evaluation is in its final phase prior to the award of a subcontract.
