Aerial Operating Theatre: An Electromagnetically Suspended Surgical Platform for In-Transit Damage Control Surgery During Mass-Casualty Disaster Evacuation

In mass-casualty disasters, a subset of victims have injuries — tension pneumothorax, exsanguinating haemorrhage, traumatic brain herniation, traumatic aortic injury — whose physiological window to death closes before a helicopter reaches a receiving hospital. Current air ambulance platforms cannot address this: rotor-induced vibration at 10–30 Hz and 0.5–2.0 g amplitude renders surgical instrument precision physically impossible, and attitude excursions of ±10–20° produce 100+ mm fluid redistribution across an open operative field. This paper proposes the Aerial Operating Theatre (Aerial OT) — a hybrid surgical pod electromagnetically suspended from the helicopter fuselage, mechanically decoupled from the airframe, with passive counterweight gravitational alignment. Surgeon and patient move together as one isolated body; relative displacement between them approaches zero regardless of aircraft motion. The paper provides quantitative EM force and current analysis (13–16 A DC lower coils, 7–8 A upper coils), thermal management specification (1.7–2.6 kW resistive heat, 1.9 L/min water cooling loop), and EMI shielding analysis showing unshielded coils exceed MIL-STD-461F RE101 avionics limits by 330× at 1 metre, mitigated by 3 mm mumetal coil housing (shielding factor S=600). Platform feasibility analysis identifies the Mil Mi-26 as the primary candidate. A three-stage prototype validation pathway (bench-scale, ground test, airborne evaluation) is proposed with a 4–6 year timeline to first manned surgical evaluation. This is a conceptual engineering framework; no prototype has been constructed.
