Orbital UAV Engine and Propulsion Systems Compared to other UAV Engines:
Spark Ignition Technology for Heavy Fuel UAV Engines
FlexDI™ is proven direct fuel injection technology able to offer an advanced Spark Ignition solution for UAV engines including Gasoline, JP5, JP8 and JetA. FlexDI™ is also able to be used for spark ignited Diesel applications.
Key benefits of Orbital’s FlexDI™ heavy fuel UAV technology:
Multi-fuel capability with same hardware: gasoline, JP5, JP8, Jet A
Cold start capability down to -35ºC without the use of heaters
~30% reduction in fuel consumption at cruise conditions because DI enables lean stratified operation – typical brake specific fuel consumption at cruise of 330g/kWh (0.543lb/hph)
Lower fuel consumption that 2-stroke carburetted/EFI or gas turbine engines
Lower vibration signature and lower weight than compression ignition (diesel) solutions.
Orbital’s design experience ranges from the application of fuel injection systems, development of small engine non-automotive 2-stroke and 4-stroke applications, through to multi-cylinder head and engine design to automotive specification. This breadth of experience and Orbital’s significant database of engine designs and engine performance characteristics places Orbital in a strong position to assist OEMs to meet the ever changing legislative and market requirements. Engines for a number of industry leading UAV customers have been developed at our technical centre in Perth, Western Australia. This facility offers a full complement of engineering design, prototype, validation and production capabilities to take your engine from concept to product.
CFD / FEA / Analysis
Design engineering capabilities include:
Clean sheet engine design based on application package and performance requirements
Design and system Failure Mode Effects Analysis (FMEA)
Finite Element Analysis (FEA) of engine and sub-systems to improve reliability and reduce weight
Optimization of all existing gasoline engines for improved reliability, fuel consumption and performance.
Implementation of electronic fuel injection (EFI) systems; both conventional port or direct injection technologies
Orbital’s engine facilities can be utilized to assess engine performance, fuel consumption, vibration and durability under a range of operating conditions, including environmental. We have the capability to run engines in aero configuration, including:
Aero-Engine propeller test stands (including durability cycles such as FAR33)
Simulated altitude testing (including control of both ambient air temperature and intake / exhaust pressure conditions)
These development facilities are now also available through the engineering consultancy to other UAV developers working on developing, calibrating and validating their own products. We can also provide on-site propulsion engineering support for your lab and flight testing programs.
