Electromagnetic Maneuvering Flaps

Yet another shortfall of the F-20 in comparison to the F-16 was the instantaneous and sustained turn rates. The F-20 was the best gun platform flying, with the most stable point-and-shoot capability in the air. Yet, like all of the other differences between the F-16 and F-20 that the Koreans flung in Northrop's face, this was one that management decided had to be addressed. The thin 1950's-vintage supersonic wings of the F-20 allowed no conventional technical solution. Therefore the engineers decided they would, for the first time in a combat aircraft, use electromagnetic actuators together with new maneuvering flaps which would increase the effective wing area in maneuvering situations by 10%. These infinitely-variable flaps would allow the F-20 to out-maneuver the F-16 in all situations and were the wedge that could lead to later F-20 models being 'all electric' aircraft, with no hydraulic actuators, accumulator, pumps, or lines. However it was yet another (virtually!) leading-edge technology. For a while it looked like the disc-shaped actuators could not be thin enough to fit into existing wing mold line. There was even the possibility that aesthetically-disastrous-but-aerodynamically-inconsequential bumps would have to protrude from the wing surface to accommodate the actuators. Fortunately it was found the actuators could actually be built within the specified depth, and the bumps would be unnecessary. Development of the actuators was another element of the production-model F-20 that was barely begun at cancellation, but could have resulted in significant development and production delays, risks, and extra costs.
