STEP 2: INSTALL ENGINES AND CONTROL SYSTEMS The second step in Support Vehicle design is the installation of the vehicle’s engines and control systems. This step establishes the key factors in the Support Vehicle’s mobility, including the size and performance of its engine and the weight of the control systems the crew uses during operations. INSTALL ENGINE Each Support Vehicle carries one engine to power its movement, equipment and other integral components. As Support Vehicles use a wider set of standards than Combat Vehicles, the formula for determining the vehicle’s engine weight is slightly more complex than that for a Combat Vehicle, and factors in the Support Vehicle’s engine type, Technology Rating and desired speed as well as the unit’s overall weight. Support Vehicles do not use the military engines shown on the Master Engine Table (p. 49). The Support Vehicle Engine Table below provides the formulas and compatibilities of the various engine types available to Support Vehicles, by Tech Rating. Determining the weight of a Support Vehicle’s engine is simply a matter of multiplying the vehicle’s total weight by its Base Engine Weight (a base multiplier of the vehicle’s total weight based on its size and motive type), Movement Factor (a value derived from the unit’s desired Cruise/Safe Thrust) and Engine Weight Multiplier (a value based on the type and Tech Rating of the engine chosen). This fi nal weight (rounded to the nearest kilogram for Small Support Vehicles, and to the nearest half-ton for those weighing 5 tons and up) includes the engine, transmission and any integral cooling systems and shielding necessary to operate the engine. If the compatibility of an engine type is noted as “N” (under its respective Compatibility column on the table) for a given Support Vehicle motive type, that engine type may not be installed on that Support Vehicle. If a given Engine Weight Multiplier for a Tech Rating is listed as “NA” (under its respective Multiplier column on the table), that engine type is unavailable at that Tech Rating. At the designer’s option, a Support Vehicle may mount an engine at a diff erent Tech Rating than its chassis (either higher or lower). If a higher-rated engine is used, however, it will drive up the Support Vehicle’s overall Tech Rating accordingly. Minimum Engine Weights: In Support Vehicle design, Fusion engines of Tech Rating C, Fission engines of all Tech Ratings, and all hover-based Support Vehicles have minimum engine weights that must be satisfi ed during construction. For Fission engines (and Fusion engines of Tech Rating C), this minimum engine weight is 5 tons (5,000 kilograms), regardless of the Support Vehicle’s size, weight, speed or motive type. For Support Vehicles with a hover motive type, this minimum weight is equal to 20 percent of the vehicle’s total weight, rounded up to the nearest kilogram for Small vehicles, or to the nearest half-ton for hovercraft 5 tons and over. If both of these conditions apply (for example, a hovercraft powered by a Fission engine), the higher weight result applies. If the computed weight of the vehicle’s engine is less than this minimum, the designer must either increase the vehicle’s speed until an engine weight that meets the above criteria is found, or infl ate the engine’s weight to meet these minimums without increasing performance. For example, a 4,500-kilogram hovervan with a minimum engine weight of 900 kilograms (20 percent of 4,500 kg = 900 kg) may install an engine that provides 6 Cruising MP at 600 kg if desired. In order to meet its minimum engine size requirement, however, this engine will be “infl ated” to 900 kg without changing its performance. Tractor/Trailers: Support Vehicles built as Trailers (constructed using the Trailer chassis modifi cation), do not require an engine or control systems unless they are also expected to operate without a suitable Tractor unit. The movement rate of any Tractor/Trailer Support Vehicle combinations is based off that of the controlling Tractor unit, and is subject to the rules for carrying external cargo as presented in Total Warfare (see p. 261, TW). Tech Base/Rating: The engine types and Tech Ratings presented in this section are available to Support Vehicles made using either the Clan or Inner Sphere tech bases. Support Vehicles created under either technology base may not make use of the combat engines shown on the Master Engine List, including Compact, Light and XL Fusion engines. Space: The types of engine used by Support Vehicles do not aff ect the Support Vehicle’s equipment slot space. Support OmniVehicles: Engine type, Tech Rating, movement points and weight must be established when designing a Support OmniVehicle’s base confi guration, and may not be altered in the completed Primary or Alternate configurations of that Support OmniVehicle.
