EXPERIMENTAL PROTOTYPE PACKAGE VENTILATION KIT, FIRST STRUCTURAL AND HUMAN FACTORS TEST
Abstract
A structural test and human limit evaluation of the shelter Package Ventilation Kit (PVK) showed that the ventilator can be readily operated for periods of at least three hours with 7-1/2 minutes rest each half-hour. The PVK can be operated at pedal speeds from 45 to 63 RPM, and the preferred speed was 55 RPM. The optimum power input was found to be 0.10 horsepower per operator, and the maximum tested was 0.15. Most tests were performed at comfortable conditions, 68 to 72 F effective temperature (ET). The maximum ET imposed was 83 F. Further tests are required to establish work/rest cycles when operating the PVK at elevated ET's.
