Development of Advanced Sled Velocity Measuring Techniques Covering Trackside Magnetic VMS and On-Board Magnetic VMS.

摘要

The Test Track facility at Holloman AFB,New Mexico operates rocket sleds for developmental test purposes at speeds into the high supersonic regime. A fundamental requirement on all track missions is a knowledge of instantaneous sled velocity as a function of time and position. This report presents some historical background and discusses the evolvement of two basic velocity measuring systems. The distinct purpose and function of each system as well as the need for upgrading the two systems is shown. The development of two magnetic systems fulfilling present day requirements is described and discussed in detail. A brief treatment of data analysis is given and a comparison of the magnetic on-board system with respect to the standard optical system is given. (Author)
