Laboratory thermodynamic tests have been performed on an operational prototype of the Sonar Target Vehicle. The Sonar Target Vehicle simulates the dynamic and acoustic characteristics of modern submarines for fleet sonar and magnetic anomaly detection training. With the present vehicle configuration the on-board electronic and mechanical systems are subjected to internal heating within the hull. A recirculation cooling system was designed to provide the necessary heat rejection and maintain acceptable temperatures throughout the hull. The adequacy of the cooling system and the vehicle thermal performance limits in terms of interior temperature were established. In addition, during these tests operational procedures were established for handling the vehicle and confirmed revised battery handling and charging techniques. Finally these tests verified the adequacy of a revised design which replaced a planned vehicle compressed air cycle cooling system with a centrifugal air blower recirculation system.
