Center for Thermal Spray Research: Spring 2019 Consortium Meeting
Abstract
Army ground vehicles are subject to a range of vehicle-level requirements that impact the design and selection of the power plant.1. Duty cycle-The combat vehicle duty cycle is more heavily weighted toward low-load when compared to on-road commercial trucks.2. Reliability versus durability-The lifetime of a combat vehicle is significantly less than a commercial truck. In peacetime combat vehicles cover less than 1,000 miles per year whereas commercial trucks accumulate up to 250,000 miles annually. Additionally, the inability of a combat vehicle to operate in the critical moment may be fatal. 3. Extremes of operating conditions-Combat vehicles are required to operate at extreme ambient temperatures from -60 to 120F while maintaining vehicle propulsion requirements (e.g. top speed, gradeability, acceleration, etc.). Additionally, the terrain that these vehicles operate over are extreme and may include paved roads, snow, ice, sand or mud.4. Armor enclosure-The entire propulsion system is enclosed in armor for combat vehicles. Ballistic grilles are used on air inlets and outlets which can drive up the cooling system fan power to as much as 10 to 15 percent of propulsion system power.
