International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The yawsonde is a device used at the U.S. Army Research Laboratory (ARL) to investigate the in-flight behavior of spinning projectiles. The standard yawsonde consists of a pair of solar cells and slits that respond to solar rays. The sun is used as an inertial reference to measure the pitching and yawing motions of the projectile. An FM telemetry package transmits the sensor data to a ground receiving station for analysis. The standard yawsonde package is housed in an M577-type artillery fuse body. The spinning motion of the projectile serves as the sampling rate for the measurements. When the spin rate is not significantly higher than the yaw rate, multiple sets of sensors must be used to effectively increase the sampling rate. The pinhole yawsonde sensor was developed for projectiles that require multiple sets of sensors in a very limited space. This pinhole yawsonde consists of a number of sensors located behind pinholes placed around the projectile's circumference. Since each pinhole makes a yaw measurement, many measurements, or samples, are taken with each projectile spin revolution. More pinhole sensors may be added to increase the measurement sampling rate. One application of this yawsonde is to aid in evaluating the performance of tactical devices and inertial systems onboard projectiles with limited space for instrumentation.

This thesis examines a single-stage barrel-less electromagnetic induction launcher, developed from an arrangement used previously for very high speed, low projectile mass accelerators. The projectile is placed on top of the launch coil, rather than inside the coil, as is more usually the case in both single and multi-stage launchers of this type. The examination is undertaken both theoretically and experimentally, with extensive experimental results being used to test the validity of the theoretical techniques used. The theoretical examination of the launcher is based on two distinct mathematical models, with results provided by the two approaches being compared. The first model uses a 2D electromagnetic finite-element approach, and does not include projectile motion or thermal effects. It is used to establish whether an analysis technique which does not take into account the projectile dynamics is a valid design tool for a single-stage launcher. The second model employs a coupled-circuit approach to take into account both projectile motion and thermal effects, and is used to obtain an accurate estimate of the overall launcher performance. With the aid of the two models the effects of varying many different launcher parameters are examined, including the size and shape of the stator coil and the size, shape and composition of the projectile. The launcher investigation could be based on a number of criteria but here it is primarily based on two; the highest average velocity over a given distance and the shortest time required to travel a given distance from the initial stationary position.
