    • A reconfigurable model rocket that can be flown either in a single-stage or a two-stage configuration is disclosed. The model rocket has a main body tube, a nose cone, a first tail section, a second tail section, and a staging adapter. The nose cone is removably coupleable to a top end of the main body tube and the first tail section is removably coupleable to a bottom end of the main body tube. The first tail section accommodates a first rocket engine to propel the model rocket by allowing gases from a combustible propellant to escape from the bottom end of the first tail section. The second tail section is removably coupleable to a bottom end of the first tail section and accommodates a second rocket engine to propel the model rocket by allowing gases from a combustible propellant to escape from the bottom end of the second tail section.

    • A ducted fan type model aircraft power plant having a mounting for a one cylinder internal combustion model aircraft engine. The preferred engine utilized a special vertically oriented carburetor. A duct is supported by a set of stators having an aerodynamic shape for straightening airflow through the duct. A fan having seven identical individual replaceable blades is disposed at the front of the duct and directly driven by the engine. One stator is adapted to essentially enclose the vertical carburetor and to smoothly direct the airflow from the fan around the carburetor to the engine cylinder for cooling. The stator has an opening to the carburetor air inlet for providing air under pressure thereto. The stator shapes cooperate with the duct and aft fairings of the power plant to deliver a smooth airstream having a uniform non-turbulent flow to produce a maximum propulsive efficiency.

    • A line-controlled, centrifugal fan, jet-propelled model airplane is disclosed in which the impeller of a fan contained within the fuselage of the aircraft is driven from a remote drive unit by an elongated flexible cable contained within a flexible sheath. The impeller rotates about an axis perpendicular to the longitudinal axis of the airplane and is driven in a direction of rotation tending to rotate the airplane about its lateral axis in a nose-up direction, due to the frictional contact of the compressed air between the rotating impeller and the housing of the centrifugal fan mounted within the fuselage. A flywheel powered by the electric motor in the remote drive unit controls the rate of acceleration and deceleration of the aircraft as an electric motor in the drive unit is switched on and off.

    • A toy rocket has a motor receptacle designed to receive a rocket motor of the type fueled by a self-pressurizing liquid propellant. The rocket motor during the fueling operation has its nozzle seated in a launcher through which liquid propellant flows into the propellant cavity of the rocket motor. When the propellant cavity of the rocket motor is pressurized, a member responsive to propellant pressure in the rocket motor engages a portion of the walls of the motor receptacle in the rocket body. When the pressure responsive member releases the receptacle walls, relative motion is provided between at least a portion of the rocket body and the rocket motor. For example, in one embodiment of the toy rocket, a second stage portion of the rocket is spring-biased away from a first stage portion of the rocket body. The major section of the rocket motor is fixed to the first stage portion. The pressure responsive member on the rocket motor engages the second stage portion while the rocket motor contains propellant to prevent separation of the first and second stages. When the propellant is expended, the pressure responsive member releases the second stage, allowing separation of the second stage from the first stage. A parachute is then deployed from the second stage to brake the descent of the rocket.
    • 玩具火箭具有设计成接收由自加压液体推进剂燃料类型的火箭发动机的马达插座。 加油操作期间的火箭发动机的喷嘴位于发射器中,液体推进剂通过该喷射器流入火箭发动机的推进剂腔。 当火箭发动机的推进剂腔被加压时,响应于火箭发动机中的推进剂压力的构件与火箭弹体中马达容座的壁的一部分接合。 当压力响应构件释放容器壁时,在火箭主体的至少一部分与火箭发动机之间提供相对运动。 例如,在玩具火箭的一个实施例中,火箭的第二台部分被弹簧偏压远离火箭主体的第一台部分。 火箭发动机的主要部分固定在第一阶段部分。 火箭发动机上的压力响应构件接合第二级部分,而火箭发动机包含推进剂以防止第一级和第二级的分离。 当推进剂消耗时,压力响应构件释放第二级,允许第二级与第一级分离。 然后从第二阶段部署降落伞来制动火箭的下降。
