Knowledge
Engineering should be visible.
REAH publishes the calculations, methods, test programmes and design decisions behind reliable aerospace systems — so engineers can apply the work and programme leaders can act on evidence.
Current technical paper · TP-001
One mission. Two engines. A system-level decision.
Peak horsepower alone cannot select a propulsion system. TP-001 examines continuous power, 45 °C operation, electrical demand, cooling integration and life-cycle burden across a defined low-altitude UAV mission.

REAH Technical Paper Series
One connected engineering programme.
A series on the propulsion, cooling, airflow, electrical and harsh-environment decisions that determine whether small aircraft and UAVs work where they are needed. Each paper is published when the underlying engineering supports it.

Engineering notes
Methods and decisions, explained.
Shorter publications explain the physics, assumptions and engineering decisions behind reliable aerospace systems. Programme evidence belongs in Engineering.
Component sourcing database
Sourcing data for engineers, gated to genuine programme work.
A working reference database covering engines, alternators, propellers, cooling systems and ECUs — built to support programme teams sourcing, testing and verifying components, not for open browsing.
Tools from the work
Engineering methods, made reusable.
REAH CFD Studio and the Rotax Cooling Toolkit turn repeated analysis into controlled, inspectable workflows.
Bring REAH an engineering question worth investigating.
The strongest programmes begin with a precise operational problem and a clear standard of evidence.
