Adr Propulsion Wheels
A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components.

The function of the drivetrain is to couple the engine that produces the power to the driving wheels that use this mechanical power to rotate the axle. This connection involves physically linking the two components, which may be at opposite ends of the vehicle and so requiring a long propeller shaft or drive shaft. The operating speed of the engine and wheels are also different and must be matched by the correct gear ratio. As the vehicle speed changes, the ideal engine speed must remain approximately constant for efficient operation and so this gearbox ratio must also be changed, either manually, automatically or by an automatic continuous variation.
The final drive is the last in the set of components which delivers torque to the drive wheels. In a road vehicle, it incorporates the differential. In a railway vehicle, it sometimes incorporates the reversing gear. Examples include the Self-Changing Gears RF 28 (used in many first-generation diesel multiple units of British Railways) and RF 11 used in the British Rail Class 03 and British Rail Class 04 diesel shunting locomotives.In a motor vehicle, the powertrain consists of the source of propulsion (e.g. the engine or electric motor) and the drivetrain system which transfers this energy into forward movement of the vehicle.
Howe Industries has been the recipient of multiple grants from federal agencies, including NASA (and NASA NIAC), DARPA as well as the NSF. In addition to the ThermaSat CubeSat propulsion system, Howe Industries has developed the solid-state, Advanced Thermoelectric Generator (ATEG), new fuel for nuclear thermal propulsion, and the even more high-tech nuclear Pulsed Plasma Rocket. Other projects range from debris de-orbiting to a rover for the surface of Mercury (which will be both powered and cooled using ATEG). The company is also investigating the application of their extensive knowhow towards the development of a compact fission-power station for the envisioned lunar base.
Howe Industries is investigating a system that may produce 20,000 lbsf of thrust with an Isp of 5,000 s. The system is derived from the Pulsed Fission Fusion  concept but the Pulsed Plasma Rocket (PPR) is smaller, less complex, and more affordable. The performance of a propulsion system with high Isp and high thrust allows missions throughout the solar system and beyond which are not possible with current technology. Human missions to Mars in two months are possible. 041b061a72
