Modified a/B45y-1 Biological Spray Tank System (Phases I, II, and III).

摘要

The existing A/B45Y-1 Biological Spray Tank was modified to incorporate a wind-driven electrical generator to power the tank heater system, thereby making the tank independent of the carrying aircraft for this service. The generator was mounted to the nose of the tank using a new aluminum nose cone which interfaced with the existing nose cone attachment points located on the forward bulkhead. Weight and balance was adjusted by the addition of ballast weights attached to the aft bulkhead. In addition, the tank electrical control circuitry was redesigned to ensure complete operational compatibility of the tank with the existing aircraft control wiring and the variety of umbilical connector types and locations at the numerous pylon stations on the various designated aircraft (F-4C, F-105, F-100). As modified, the tank was subjected to environmental testing and incurred damage. An analysis of the test data indicated that the generator and its attachments were being subjected to excessive loads due to the flexing of the tank plastic centerbody. It was concluded that the existing tank structure, which could not be readily modified, did not lend itself to the mounting of additional weight at its extremities. (Author)
