A Voith-Schneider cyclogyro propulsion concept for UAM, holographic particle detection with a drone, new UAV licensing requirements in Singapore with stiff penalties for non-compliance, Pipistrel plans an autonomous heavy lift UAV, the EU looks to police its southern border with medium-altitude long-endurance drones, maintaining offshore wind farms with autonomous drones, and drone seeding to save the Koala.
CycloTech is an Austrian company that is developing a propulsion system based on Voith-Schneider propellers, which the company calls “cyclogyro rotors.” The system combines characteristics of helicopters and conventional propeller blades. CycloTech plans to fly a demonstration model by the end of the year.

The “Holographic Aerosol Particle Imager,” or HAPI is small enough to be carried by a commercial drone and can resolve particles larger than ten micrometers in size. It can image free-floating aerosol particles from any direction and doesn’t have to actually contact the particles. HAPI uses digital holography and is built from 3D-printed polymer structures
The paper Imaging atmospheric aerosol particles from a UAV with digital holography published in the journal Nature Scientific Reports tells more.
The Civil Aviation Authority of Singapore (CAAS) announced that starting February 2021, if you are 16 years old or above and want to fly a drone above 1.5kg in weight, you must complete online training and pass an exam to get licensed. If you are under 16 years old, you must be supervised by an older licence holder.
There are two different certificates: An unmanned aircraft basic training certificate for those flying drones between 1.5kg and 7kg for recreational or educational purposes, and an unmanned aircraft pilot license for those flying drones above 7kg or who are flying them for commercial purposes. Penalties for flying drones without the appropriate licenses include jail time and fines up to $100,000 or both.
Pipistrel Aircraft is developing the Nuuva V300, a long-range large-capacity heavy-weight autonomous eVTOL UAV designed for aerial cargo delivery of up to 460 kg. Power comes from eight Type Certified battery-powered Pipistrel E-811 electric engines. Entry into service is planned for the second half of 2023. The smaller Nuuva V20 is targeted at last-mile delivery...
