However, wing sweep angle is used for high-speed aircraft.

If an aircraft's maximum speed is less than 0.3 Mach, wing sweep is not recommended. The aspect ratio (AR) of the high-speed decoy wing was 5, and taper ratio value was 0.36 from other successful aerial target designs. The wing incidence angle was 0 degrees for this decoy design because the wing incidence angle is generally set at 0 degrees for mid-wing jet fighter aircraft. The mid-wing configuration was selected because it had the properties of high- and low-wing it also had the lowest drag from wing-body interference. From this, the advantages and disadvantages of high-wing, mid-wing, and low-wing configuration types were considered. Wing GeometryĪfter considering the catapult, maneuver, and cruise constraints, the wing loading at takeoff condition was calculated as 23.209 lb/ft 2, which is the maximum that it should experience. The required payload capacity was 22 lb, consisting of a smoke dispenser, a passive radar cross section augmenter (luneberg lens), a chaff and IR dispenser, and a miss distance indicator. This aircraft design had a 6-g sustained and 9-g instantaneous load factor. The highly agile decoy UAV with high maneuverability capability was designed to launch from a pneumatic catapult and land via a parachute. The mission requirements for the high-speed decoy were a maximum altitude of 15,000 feet with maximum speed of 450 knots and an endurance of at least one hour.

In this study, computational fluid dynamics (CFD) embedded in CAD software was used to optimize the aircraft design and test the aircraft performance during different operations such as cruise, maneuverability, and maximum speed.

A baseline high-speed decoy design CAD model The system picks up the signature of the drones and attacks them while the actual aircraft can be hidden with the swarm of drones. If operating as designed, one or more drones are launched from an actual aircraft as it enters airspace monitored by anti-aircraft systems. These drones are intended to confuse or mislead anti-aircraft defense systems. One area of increasing interest is the decoy drone, designed to mimic the radar and heat signature of an actual aircraft. Drone aircraft and their uses have been evolving quickly, supported by a great deal of ongoing research.
