    • A method is disclosed for controlling a flight trajectory of a spinning projectile. In one aspect the method may involve supporting a nose of the projectile in a manner permitting the nose to be wobbled. At least one electrically responsive component may be coupled at a first end to the nose and at a second end to a base portion of the projectile. An angular position of the nose of the projectile may be sensed as the projectile flies through an atmosphere after being fired from a weapon. An electrical signal is controllably applied to the electrically responsive component, in relation to the sensed angular position of the nose, to control an attitude of the nose during flight of the projectile.

    • A piezoelectric transducer able to convert an electrical signal into a mechanical motion. In various embodiments the transducer is used to form a motor and an actuator. In one embodiment a piezoceramic stack is supported as to experience a compressive load from a flexible beam. The flexible beam is installed under compression to assume an initial bowed shape. Applying an electrical signal to the piezoceramic stack causes decompression, and thus lengthening, of the stack. This in turn causes an increased compression of the flexible beam that causes it to flex from its initial bowed shape to an increased (i.e., more pronounced) bowed shape. An output member disposed against the flexible beam is driven by the flexing of the beam. Alternately applying and removing the electrical signal causes an alternating mechanical motion to be applied to the output member by the flexible beam.
    • 能够将电信号转换为机械运动的压电换能器。 在各种实施例中,换能器用于形成马达和致动器。 在一个实施例中,压电陶瓷堆叠被支撑以经受来自柔性梁的压缩载荷。 柔性梁被安装在压缩下以呈现初始的弯曲形状。 将电信号施加到压电陶瓷堆叠导致堆叠的减压并因此延长。 这又导致柔性梁的增加的压缩,使得其从其初始弯曲形状弯曲到增加(即更明显)的弓形。 抵靠柔性梁设置的输出构件由梁的弯曲驱动。 交替地施加和移除电信号将导致交替的机械运动通过柔性梁施加到输出构件。

The system includes first and second electrode layers each including two electrode sections, an intermediate electrode layer between the first and second electrode layers, and first and second electrostrictive materials that change length in an applied electrical field. The first electrostrictive material is positioned between the first and intermediate electrode layers. The second electrostrictive material is positioned between the intermediate and second electrode layers. The first electrostrictive material has a first length adjoining the first electrode section and a second length adjoining the second electrode section. The second electrostrictive material has a third length adjoining the fourth electrode section and a fourth length adjoining the fifth electrode section. The first and second electrostrictive materials are attached such that differential changes in the first and third lengths, and the second and fourth lengths, respectively, results in a compound lateral motion.

    • A preferred rotary actuator includes an actuator assembly having a torque tube formed of a shape memory alloy (SMA), a superelastic NiTinol return spring associated with the torque tube and adapted to bias the torque tube toward an initial position, and a torque tube heating element, especially a thermoelectric device, for switching the SMA to cause rotation to an object connected to the actuator or to generate a torque upon that object. The torque tube (24) includes a proximal end (32) and a distal end (34). The return spring and torque tube are connected at their ends, with the torque tube being pretwisted while in a martensitic state relative to the spring. Activation of the heating element causes the torque tube to enter an austenitic state in which it returns to its previous untwisted configuration. Removal of heat allows the torque tube to return to a martensitic state, when the return spring retwists the torque tube. A unique locking assembly 22 is used with the preferred actuator assembly. A helicopter blade twist rotation system for a rotorcraft blade 200 having a blade root 202 and a tip 204 includes a SMA rotary actuator 18 located within the blade near the blade root, and a passive torque tube (206) located within the blade and having a proximal end connected to the rotary actuator and a distal end connected to the blade near to the blade tip.
