The ethics of BF Turbines and Behotec is very simple: use the best material and processes available in Germany to produce the highest quality turbines at a reasonable price. The highest quality controls are applied to the material and machining processes insuring the highest reliability and performance to all our engines. Each engine comes with its own test bench report and data sheet.
All the components are designed and produced in house ( including Inconel cast components and laser welded parts), enabling a perfect mastering of the quality, reliability and efficiency of the engines. The engines thermodynamic cycle and aerodynamics have been defined and optimized on computers with a famous CFD ( Computational flow design ) software called ANSIS. The engines are then CAD designed and digitally produced with state of the art German CNC machines.
The JB-190 is a new addition to our Behotec engine line. This is the mid engine to the legendary 160 format Behotec line, featuring a lower price and phenomenal thrust to weight ratio. Behotec was able to drop the price of this engine thanks to part commonality with the other bigger brother in the line; the JB-220.
This engine features the following specific points:
Laser cut and welded full Inconel combustion chamber (world premiere).
Custom machined Inconel fuel sticks with stainless steel diffuser needles.
Bespoke ceramic burner with specific positioning enabling very positive and predicable starts.
Bespoke in house designed and produced Inconel turbine wheel and CNC Machined NGV.
Patented self centering rear bearing system. Including exclusive lubrication and cooling pattern keeping this area of the engine very cold.
Integrated temperature sensor with TGT reading (not an EGT reading: much more predictable and precise but reads higher temperatures than an EGT because it is located in front of the turbine wheel).
The all new exhaust pipe and inner cone are CNC machined from billet high temperature steel.
They feature 6 Laser welded fastening tabs ( world premiere ) and 12 fastening screws with a specific high tolerance seal.
The new exhaust flange is slightly conical and is completely sealed thanks to tight tolerances and a small lip on the outer casing.
Anodized CNC machined bracket including rivnut system for easy fastening.
Unique fully anodized engine for maximum durability with a specific color scheme.
High flow fuel pump with specific large bore fuel lines
Bespoke high flow fuel valves offering 50% higher flow than standard electronic valves.
High frequency Hornet III ECU enabling very accurate engine control.
Best fuel efficiency and power-to-weight ratio of the market.
Best price-to-thrust ratio of the market.
