This is the all new 140 N engine from BF. It features the highest power-to-weight ratio on the market for this segment: 140N in a 100 N form factor!
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.
They are the only engines on the market featuring all Inconel internals!
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 ANSYS. The engines are then CAD designed and digitally produced with state of the art German CNC machines.
All aluminium and steel design: no plastic parts are present on the engine except for the plugs.
High quality dual ball bearing starter motor.
Black diamond anodized inlet and compressor on the BF engines ( world premiere ) enabling a very high resistance to dust abrasion of these parts.
CNC machined compressor, diffuser and outer casing from aero grade aluminium billet.
CNC machined engine shaft made from high tensile steel.
State of the art GRW 6000 series ceramic/ ceramic bearings made in Germany.
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 patterns 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 ).
Exhaust pipe and inner cone CNC machined from billet high temperature steel, including 6 Laser welded fastening tabs ( world premiere ) and 12 fastening screws with a specific high tolerance seal.
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
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.
Service interval: 50 hours max.
