Confined-Space Inspection Blimp
An explosion-proof aerial inspection concept investigating buoyant helium envelopes, low-energy micro-thrusters, and collision-tolerant soft hulls to inspect industrial storage tanks without turbulence or ignition risk.

Zero-Spark Buoyant Confined Vessel Survey
- ✓Eliminates crash damage risks through inherently gentle buoyant helium lift.
- ✓Draws minimal electrical current compared to drones, drastically reducing spark ignition potential.
- ✓Bounces harmlessly off internal baffle walls and structural roof trusses.
The Engineering Challenge
Problem / Objective
Conventional multirotor drones generate intense propeller downwash that kicks up toxic tank sediment and risk battery-puncture sparks.
