Megawatt Electric Aviation Dyno Test Cell Rigging & EMI Audit
Engineering protocols for rig-in of high-speed dynamometer torque reaction bases, pneumatic seismic air-spring suspension, Faraday cage electromagnetic shielding, and dual-hoist cleanroom positioning.
01 Seismic Inertia Reaction Base & High-Frequency Vibration Isolation
Testing megawatt-class electric aviation powertrains requires rigorous dynamic containment. At full load, 3 MW dyno units produce over 1,200 Nm of high-frequency oscillatory torque at 24,000 RPM. If coupled directly to standard concrete shop floors, dynamic resonance would damage facility structures and introduce measurement noise. The test bed must float on an isolated 180-ton post-tensioned inertia block supported by active pneumatic air springs.
Pneumatic Leveling Air-Springs
Low-frequency (1.2 Hz natural frequency) elastomeric air-mount bellows dynamically level the inertia block with closed-loop optical height sensors maintain ±0.1 mm plane.
Faraday RF Shielding Seals
Beryllium copper finger-stock gaskets and continuous seam-welded copper wall panels attenuate EMI/RFI noise from high-frequency SiC inverters up to 100 dB across 10 kHz – 18 GHz.
Burst Containment Armor Ring
Heavy 50 mm thick forged alloy steel containment rings line the dyno rotor envelope to arrest any high-energy fragments in the event of an uncontained rotor burst.
02 Dyno Dynamic Torque Reaction & Anchor Bolt Stress Simulator
Evaluate continuous and short-circuit fault torque reactions, anchor bolt shear stresses, and foundation overturning safety factors during high-power aircraft test runs.
03 Cleanroom Dual-Hoist Rigging & Thermal Expansion Offset Alignment
Overhead cleanroom crane utilizes non-shedding Dyneema slings and stainless steel hook blocks to hoist the 25-ton absorber into the cell airlock.
Pneumatic air-skate dollies glide the unit across ultra-smooth epoxy flooring into position over the seismic reaction block T-slots.
Multi-beam laser alignment targets calculate cold misalignment offsets (−0.12 mm vertical) to allow for thermal growth at 180°C operating temperature.
Hydraulic torque wrenches preload all M36 anchor studs to 550 Nm with nord-lock wedge washers and vibration-resistant thread-locking compound.
