Welcome To McCotter Technologies New And Innovative Electric Technologies And Applications For The 21st Century Turbo Electric Engines McCotter Technologies Turbo Electric Engine (Mod 1) The McCotter Technologies Turbo Electric Engine is a DC Powered, Three Stage, Dual Spool, Multi-Speed Axial Compressor engine that utilizes Gearless Reduction Technology in 2.0 to 1 and 2,8 to 1 speed ratios. The engine in the photographs is the first to be constructed in mock-up and later prototyped for test cell anaysis,. Further construction and testing was halted due to insufficent captial resources. The 3D Model above has the Flow and Pressure shrouds removed to provide view of internal components. The turbine engine is well stated as it developed and passed through history as one of our greatest developments. The Turbo-Electric engine is at the beginning of it's development and stands in a position to create it's own history. FrontRear Engine pictured has two stage, variable compressor bleed. Accessories shaft driven by geared PTO . McCotter Technologies Turbo Electric Engine (Mod 2) The Model Two Engine, like the original design, has multi-stage, multi-speed configurations that fully utilizes the Braden cycle to genrate power and output. In this model, the forward low pressure compressor was increased in size to increase High Pressure Turbine performance. McCotter Technologies Turbo Electric Engine (Mod 3) The Model Three engine was designed as a High By-pass Flow engine similar to the Super Fan engines found on many large commercial aircraft. The main core engine provides power to the Forward By-pass fan. However, it is also the basis for the standard Mod 3 turbine (pictured below ) that is used in the McCotter Technologies Turbo Electric Car. Turbo- Electric DC Motor Dynamics The key to the Turbo-Electric Engine is of course the size and power of the electric motors that are enployed. But, it is not power or torque that concerns us the most. One of the most important dynamic to consider is RPM. The motor must be powerful enough to turn the compressors yet still be able to provide the high RPM necessary to produce the thrust. The 3D illustrations above show a standard type DC motor as an example. Instead of increasing the diameter of the case and rotor, which destroys RPM by increasing the diametric rotational mass significantly, The motor is made much longer to keep the rotor diameter as small as possible, yet still provide long length and number of turns of wire to be adequately employed. Double ended shafts provide drive for both forward and aft compressor wheels. Axial turbine engines rely upon high RPM potentials rather than high torque values. Coupled with proper Compressor designs and Braden Cycle dynamics, the engine is able to perform remarkably well and efficiently. The Axial Turbine Engine developed as two primary configuration types, Single Spool, and Dual Spool. In order for the Turbo-Electric Engine to develop along similar lines. motor designs must incorporate the same operating features as previous turbine engines. Above, are two 3D illustrations showing motor designs that incorporate this dual spool principle. The Primary (inner) Shaft driving the High Pressure Compressors, while the Secondary (center) Shaft provides rotational capabilities for the Exhaust, Power Recovery Turbines and the forward Low Compressors and Fans. The concept is Revolutionary, and with newer electric motor designs and developments, the turbine engine once again has a new horizon ahead. These electric engines have many application in the transportation field. Like gas turbines, there are applications and Models that would be well suited for automotive use as well. Companies and Venture Capital entities wishing to discuss these designs, and continued development of these electric turbine engines are welcomed to forward their questions and comments ________________________________________ For more Information contact McCotter Technologies at the E-mail address below If you find you are having difficulty sending an E-mail to the address below, check your E-mail Program settings.
