The computer program, entitled 'ZDRAFT,' generates a graphic display of VTOL aircraft and their associated ground flow fields. The actual flow field data is calculated by another computer program. The 'ZDRAFT' computer code rapidly assimilates and displays this flow field data. The display consists of pertinent flow field characteristics, such as stagnation lines, upwash flow and ground plane wall jet conditions, superimposed over a scaled aircraft planform. This visual form allows easy assessment of various configurations and operating conditions. (Author)
