The Engines
ADEPT’s innovative approach to design and engineering is unique in GA, but would not be considered unusual by anyone familiar with the high tech world of Motor racing, Moto GP or the Aerospace and Defence industries. In industries that require innovative thinking, rapid but reliable product development, robust testing and validation, and mission critical performance, there are common themes and practices that make the best stand out.
ADEPT’s use of the latest technology 3D CAD packages enables virtual design and prototyping to validate form, fit and function in a concurrent engineering environment, and the use of engine design and simulation software all mean that the design stage is stable, cost effective and rapid.
In addition, all design work is done in accordance with the certification requirements of an aviation regulatory approved Design Organisation. The use of Rapid Prototyping and Additive Manufacturing has also led to shortened lead times in getting prototype engines built and tested, and advanced Finite Element Analysis, Computational Fluid Dynamics, Non Destructive Testing processes, and Casting Simulation programmes all play their part in ADEPT’s manufacturing and development programme.
The ADEPT engine range features a novel and unique (in GA) engine architecture. The 120deg V6 engine layout gives the best solution to the requirements for a lightweight, compact engine with extremely high mechanical strength and integrity, as well as excellent balance, uniform cooling, and the optimum integration of the engine/Propeller Speed Reduction Unit. Fully sequential fuel injection, a unique lubrication system, anti-backlash and cush-drive mechanisms in the PSRU all contribute to the smoothest running piston engine in GA.

Frequently Asked Questions
What is the cubic capacity of the engine?
What is the bore/stroke ratio?
Is the engine suitable for operation in non-certified helicopter applications?
Why is the ADEPT Airmotive not a compression ignition (diesel) engine?
Among the reasons for this are:
- Poor relationship between torque and power
- If used at high altitudes Jet A has to be used as it contains an anti-freeze which diesel fuels do not have
- Compression ignition engines have to be heavier to contain higher bearing loads
- Diesel engines have poor power to weight ratios
- Typical harshness of Diesel engines require complex vibration isolating solutions
- Harsh firing impulses of Compression ignition engines has a negative effect on reduction gearbox and propeller life
- Satisfactory power generation generally requires high turbo boost with related reliability problems
- Diesel fuel weighs more than gasoline
- We can meet the fuel consumption targets by using an efficient gasoline engine
