WO2024144643A1

Rib structure with fishbone imitation enabling shape change in the wing via the method of the rear spar rotation

A wing that changes its shape in flight while adding almost no weight.

The fishbone rib, with bones tapering toward the trailing edge.
FIG. 1. The fishbone rib, with bones tapering toward the trailing edge.

How it works

The ribs are shaped like a fish skeleton: a backbone with tapering bones. A motor rotates the rear spar, the rear part of each rib bends with it, and the trailing edge of the wing deforms smoothly. The aircraft can adapt the wing to each phase of flight.

WO2022216264A1

An aerostat-type unmanned aerial vehicle system for reducing air pollution

A tethered balloon that cleans the air where pollution is temporary, such as construction sites or fields where stubble is burned.

The aerostat with its filtration unit.
FIG. 1. The aerostat with its filtration unit.

How it works

A helium-filled balloon carries air filtration units with HEPA filters and an electric fan. It is powered from the ground through its tether cable and carries navigation lights, so it can stay up around the clock.
