Turbine Technics, Professional design engineering by Neil Key... 'Better By Design'

The Ultimate Two-Stage Turbine System

The TT Turbine Systems are based on reliable and tested units. We build our own Turbine System with in-house machining work, and carefully selected subcontract suppliers. We have been testing a couple of New Engine developments over the past 2 years, as well as our own 'kero start' system designated as VFS. We are now also busy with production of our Turbo-Prop system.

We have been manufacturing our own turbine parts since October 2004... initially incorporated in Customer and Development engines that had over 200 hours of test flying... and with ongoing test and development the TT-Phoenix Turbine was launched in August 2005. With further developments, we then launched a new VFS (Vaporised Fuel Start) version, originally developed for our commercial customer helicopter applications.

The Helicopter systems are now designated as the GEMINI product range, Gemini90 provides the basis for a Thrust Engine range designated as ZEUS. The new Gemini68 Helicopter system is launched in early April 2011.

The external appearance of the FOD and Starter Casing was not only designed to add style to the appearance of the initial TT-Helicopter System... but we have also taken into account ways to maximise airflow into the compressor duct (with some wind tunnel work) whilst providing a sturdy and robust casing, which supports the FOD mesh screening and electric starter. Originally designed in early 2005.

The NEW Turbo-Prop has now also undergone testing in a number of areas to provide a reliable package of engine and gearbox.

The design of the New Combustion Chamber was primarily aimed at improving the characteristics of the Twin-Stage turbine system... which also incorporates our own second-stage casings. These have allowed us to make the overall installation more compact, but still retaining our original exhaust system, manufactured in-house, and stated by most people who have seen the TT Nemesis helis in operation as "The Quietest Turbine Heli System Operating".

HELICOPTER TURBINE SYSTEM (LINK Here)

The main power unit is from our Gemini90 Heli-Turbine application and has been developed with our Turbo-Prop epicyclic gearbox over 2 years.

The Epicyclic Gearbox is designed and manufactured with our own developed components... complete with our own manufacture of exhaust. The development package is fitted to a Turbo Raven aircraft. The airframe system compnents are installed to the requirement of our experienced fixed wing pilot.

Gas start is still the standard basic option, with our own VFS as a low cost upgrade, soon it will become the standard package installation.

As usual... The turbine wheels and NGV are purchased as castings, to our drawings. They are then machined. We balance and test the Turbine Wheels, including X-Ray and Ultrasonic test.

Components are manufactured to our requirement and drawings.

For The Future... We have enlisted the help of selected jet flying specialists to help develop our own aircraft installations.

The ECU system. It is a microprocessor controlled, digital, turbine management system as well as a safety device to help prevent serious damage to your engine. It calculates the fuel supply to the engine depending on the throttle setting, the exhaust gas temperature, and rotor shaft rpm. The automatic start-up sequence helps you in this critical phase of the engine operation, controlling the fuel flow and the exhaust temperature.

The ECU is a 'Full Authority Digital Engine Control Unit'... a concept seen in full-size engine controllers and management systems.

The additional ancillary components supplied include... the electric starter motor, fuel pump, two solenoid control valves, and fuel filter. Oil is also supplied for gearbox systems, when a gearbox or complete Helicopter or Turbo-Prop system is supplied.

Currently the starter is a 280BB brushed motor, and our preference for fuel pumps is Hausl or FlightWorks. We are currently looking at other options of starter motor systems as a method of improving serviceability in long term use.

There is not much required in the way of 'additional equipment' as everything that you require, including pipes and fittings are supplied. You only need to supply the ECU battery pack, Turbine Fuel and Oil Mix, and after the final stages of assembly you are ready to 'Start the Turbine'... and we supply a Detailed Operator Manual for the operation of the Turbine and TACU ECU. The manual includes Gearbox details, and general running and service requirements for Helicopter and Turbo-Prop.

WARRANTY: Turbine Technics Turbine Systems come with a full Warranty... which varies for Turbo-Prop and Helicopter applications. Please see product pages.

Our Service Parts and Spares are competitively priced, to match the pricing policy with the rest of our products and systems.

Please see menu pages for the TURBO-PROP and HELICOPTER applications.
