For aeroplane systems the total zero lift drag was determined experimentally in the 60 x 60 sqcm supersonic wind tunnel for four Mach numbers in the range 1.56 to 4.02. These systems consist of three pointed bodies of revolution arranged in such a way that two of them are outboard lying and symmetrically arranged to the central body. Their positions were altered relatively to the central body in six steps by moving them in the spanwise direction along the interconnecting wing. Differences in total drag were obtained for 60 models.
