NASA Technical Reports Server (NTRS) · leaf 6
5 AIR FORCES ON THE SPERRY MESSENGER AIRPLANE During a test run the tank pressure was held constant; and readings of the air forces and jnomeiits tlkcn for various angles of attack. The drag and interference corrections for the attachments were determined by separate runs. … Fig. 2.—Method of supporting model RESULTS OF THE TESTS After c()iui)loling a series of five runs on the original model it was decided to add to it as much (k4aii as praclTcable in order to get a more exact geometrical similarity. Accordingly 31 chan<2:es were ma(h> as follows (figs. 3 and 4): 18.…
