Propulsion E: Electrical spirit

Patented propulsion system
The result of our approach is a so far unreached performance: a very good rate (ca. 4 m/s /790 ft/min during initial climb), a sky-scraping climb altitude (more than 3,200m / 1050 ft in smooth air) and an almost noiseless flight.
High efficiency is one side of the Antares’ innovative and patented propulsion concept. However to make an idea suitable for daily use you have to look for reliability, safety, economic feasibility and user confidence. In contrast to a combustion engine our propulsion method has a system related high operation reliability and runs almost vibration-free. Breakup- and fatigue limit problems are consequently avoided. What’s more, we only need a relatively small amount of components and all of them are high-quality parts which minimizes the risk of default.
And, last but not least: Maintaining the propulsion E costs outstandingly little time and effort compared to a conventional aircraft engine.

System monitoring
Experience has taught us that very little time is spent on monitoring the propulsion system. As long as no audio warnings are issued, the pilot assumes that the engine works perfectly and stays entirely focused on flying his aircraft.
Where possible and beneficial for safety, the main computer will use available sensors to automatically check (not override) pilot action. Some examples:
- An airbrake a warning will be issued when the pilot is working off his checklist or applying power with airbrakes extended.
- While working off the checklist a warning will be issued as long as the dolly is attached or when the landing gear switch is in “retracted” position.
- A landing gear warning will be issued once the pilot extends the airbrakes with the landing gear retracted.

Why lithium-ion cells?
Battery life
- number of charge/discharge cycles
- natural aging

Other applications
Being a user of SAFT VL41M cells, Lange Aviation is in good company. These Li-Ion cells are, among others, also utilized in most of the current European satellites. The military drone RQ-4B Global Hawk UAV, the F35 Joint Strike Fighter, the Airbus A350, and many other high-tech applications have adopted these batteries as well.
