    Abstract: A muffler devised particularly for a small, reciprocating-piston two-stroke internal combustion engine of the type used on unmanned aerial vehicles. The muffler comprises a body incorporating an inlet, an outlet, and a plurality of chambers for exhaust gas flow from the inlet to the outlet. The body is configured to present a compact profile for installation on the engine. The chambers are so configured that adjacent chambers communicate to facilitate exhaust gas flow from the inlet to the outlet via flow passages. The various chambers comprise an inner chamber, an outer chamber, and one or more intervening chambers disposed between the inner and outer chambers. The various chambers are disposed one about another in annular formation. This arrangement creates a long flow path from the inlet to the outlet incorporating various directional changes.

    Abstract: A propulsion system for a ducted fan vertical takeoff and landing aircraft (VTOL) powered by multiple electric motors with two, counter rotating electric motors comprising the primary thrust generation within a ducted fan component and 3 or more external electric motors providing lift, stability and directional control of the aircraft. Through the use of counter rotating ducted fans, the aircraft does not require the need for internal stators—either fixed or adjustable angle. Power to the electric motors is sourced by either onboard batteries, a ground based power source via a ground to aircraft tether, or an on board fuel cell or combustion engine driving an alternator.

    Abstract: An airframe (1a) having a main body (4) and a tail body, a main rotor (6) disposed above the main body (4) and driven by an engine inside the airframe (1a), and a tail rotor disposed in a rear part of the tail body (5) are provided. A pair of support legs (8, 8) at left and right sides extending downward from left and right sides in a lower part of the main body (4) and a pair of skids (9) on left and right sides provided on the lower ends of the support legs (8) and positioned out of the main body (4) in the width direction of the airframe (1a) in a front view are provided. A radiator (71) at a position more frontward than the front ends of the skids (9) in a side view, formed extendedly downward from the vicinity of a bottom surface (83) of the front part of the main body, and having wind reception surfaces oriented to the longitudinal direction of the airframe is provided. Lateral ends of the radiator (71) in the width direction of the airframe (1a) project outward beyond lateral edges of a main body bottom surface (83) in the vicinity of the radiator (71) in a front view. Further, the lateral ends (71a) of the radiator (71) are positioned inward in the width direction of the airframe (1a) within skids 9.
