Abstract
Tests have been conducted in the NAL 1 .2m tunnel on a 1/17th scale model of the MiG_21M aircraft to study the effectiveness of trailing edge flaps as manoeuvre enhancing devices, Tests were conducted at Mach numbers of 0, 5, 0 .7 and 0.9 . Schedules for deflection of flap and horizontal tail to give maximum trimmed L/D as a function of trimmed angle of attack are presented for the three Mach numbers and at two levels of static stability. The results indicate that increments of the Order of 10% in trimmed lift at angles of attack of about 12 degrees are achievable through the use of appropriately scheduled flap and horizontal tail deflections.
