摘要： A propeller aircraft for being powered by an operator moving the aircraft in a circular flight path on a tether, and adapted for emitting simulated realistic propeller and engine noises during flight. The aircraft includes an elongate fuselage carrying aerodynamic flight surfaces and at least one propeller assembly. The propeller assembly comprises a propeller shaft and a propeller hub having at least two propeller blades carried by and extending radially-outwardly from the propeller hub. The hub includes a bore therethrough for rotatably-mounting the hub on the propeller shaft. The bore is sufficiently larger in diameter than the shaft to permit axially-oscillating, non-concentric rotating motion of the propeller hub on the propeller shaft responsive to and proportional to the rate of movement of the aircraft through the air on the tether by the operator. An impact surface proximate the propeller shaft is provided for being impacted responsive to rotation of the propeller hub. The impact surface has characteristics which, when impacted, cooperate with the propeller hub to create simulated realistic multi-frequency propeller and engine noises.
