- Celeste Ecoflyers tested the inflatable wing cargo drone during early flight evaluations
- Aircraft generates aerodynamic lift without relying on lighter-than-air buoyancy systems
- Drone carried payload masses exceeding its own empty structural weight during testing
A French aerospace startup called Celeste Ecoflyers has completed early flight testing for an experimental cargo drone using a pressurised textile wing instead of rigid internal structures.
The company recently conducted short take-offs at Le Havre airport using its dAS10 cargo platform, which replaces conventional aluminum spars and ribs with inflatable architecture.
Unlike blimps or lighter-than-air vehicles, the aircraft generates lift entirely through aerodynamic principles identical to those used by conventional fixed-wing airplanes.
Inflatable wings challenge conventional aircraft design
Celeste Ecoflyers clarified this distinction publicly after earlier confusion surrounding the unusual aircraft's appearance and its inflated structural components.
The company stated plainly that “lift is aerodynamic, not buoyancy,” while explaining that only the wing structure itself...
