Experimental application equipment for the preparation of remote landing and take-off sites for turbo-jet VTOL aircraft was designed, fabricated and demonstrated. Three full scale remote sites were prepared in England and the Federal Republic of Germany. Evaluation of these sites was accomplished with the P.1127 and the VJ101C-X2 aircraft respectively. These remote sites were prepared by spraying a modified chlorinated polyester resin and fiberglass roving over essentially unprepared ground. Modifications to the application equipment, further development of materials and fabrication techniques were made as a result of the experience gained in the preparation and evaluation of these remote sites. Preliminary remote site design criteria were developed for determining site thickness, site size and shape. Experimental pads were prepared over various soil types and tested using typical wheels and tires to obtain data for determining site strength requirements. A methodology for determining site size and shape was further refined by conducting downwash flow field studies using models of the P.1127, VJ101, XC-142 and DO-31 aircraft. Dynamic pressure data obtained during remote site evaluation were correlated with model test data. Logistics support tasks for VTOL site preparation and site operation were examined.
