Comparison Between Swept and Delta Canards on a Model of a Combat Aircraft
Abstract
The aerodynamic characteristics of a low speed half model of a typical combat aircraft configuration fitted with a 65 deg delta canard planform are compared with those for the same model fitted with 44.3 deg swept canard. Both canards had an RAE 104 aerofoil section. The tests were made in the DRA 13 ft x 9 ft Wind Tunnel on a large model of the DRA High Incidence Research Model (HIRM 1), modified to represent the Experimental Aircraft (EAP) configuration. For a 15% smaller planform area, the delta canard gives higher lift and comparable pitching moments for trimming. For and wing buffeting the differences are small. Overall, these low speed measurements suggest that delta canards with round leading edges have significant advantages over swept canards for future combat aircraft.
