Design For The Uav Market

Although each of these alternative engines looks intriguing, designers might also explore additional modifications to increase their appeal to the UAV market. Already, Ecomotors has experimented with a 90% scavenging system and an electrically assisted turbocharger to further force pressurized air into the cylinders. (42) Normally powered by engine exhaust, this turbocharger is electrically powered at low rpm to boost output. (42) Although there is a slight weight penalty, these improvements alone double the power density of the OPOC engine. (42) Designers estimated that the Dyna-Cam engine, outfitted with turbocharging, would boost engine output from 210 hp to 300 hp. (34) Supercharging by using compressed air might also be considered. (19) A combination turbo/supercharging system, like Volkswagen attempted early in the millennium, resulted in a number of “best engine” awards, and a powerful, extremely efficient engine. (50E) Although the combined “twincharger” would be a pricey option, this might not be a factor for the multimillion dollar UAVs built by various military organizations around the world. Next, the alternative engines discussed above might be scaled down to provide power capabilities for smaller UAVs. MYT 's first prototype was a 14” x 14” model, weighing 150 pounds. Their second, although not yet built, is planned as a 6 inch, 25 pound, 200hp model, which would be a much more acceptable powerplant for a small to medium sized UAV. (13B) Ecomotors says
