Power Management
Electrical power generation, distribution and load engineering for aircraft where every watt is mission capability.
The Problem
UAV and special-mission payloads keep growing; the alternator on a Rotax-class engine does not. Programs routinely discover late that the electrical system — not the airframe or the engine — is the binding constraint on mission capability, especially in hot climates where cooling fans, pumps and avionics all draw more at exactly the moment generation margins shrink.
Typical Customer Questions
- How much continuous electrical power can this installation really deliver across the mission profile?
- Can the platform carry this payload without compromising engine cooling or avionics reliability?
- Where does generation, distribution or thermal derating limit us — and what are the options?
- How should loads be shed, staged or scheduled during the critical flight phases?
How We Work
- Engineer. Build a complete electrical load budget across the mission profile — generation, distribution, storage and every consumer, including the cooling system itself.
- Simulate. Model generation capability against load demand phase by phase, including hot-climate derating.
- Build. Design and prototype distribution, monitoring and load-management hardware where required.
- Test. Measure real generation and consumption in ground and flight testing.
- Learn. Compare the measured load profile with the model, identify hidden demand and update the system margins.
- Transfer. Deliver the controlled load model, monitoring method and decision logic required to manage future aircraft changes.
Typical Deliverables
- Electrical load budgets with stated assumptions and margins
- Generation-versus-demand analysis across the operating envelope
- Power-distribution and load-management concepts
- Instrumented power measurements from ground and flight testing
Evidence
Power-management engineering is part of our integrated thermal-and-power focus for Rotax platforms; development work is published through Projects as it matures.
Boundaries and Limitations
- We engineer within the engine manufacturer's electrical-system specifications.
- Published figures are labelled measured, calculated or supplier data — never blended.
