PLASMA (FALCON) FLYER 1.11 / 6 - 11 kg MTOW
Electrofluidsystems is developing a novel swarm capable high-tech mini UAV with agile flight performance and the ability for high-altitude flights through active flow control and plasma anti/de-icing on wings and propeller. The PLASMA FLYER or SWARM FLYER is made of a laser-sintered, additive manufactured, ultra-strong PEEK structure with a prepreg composite hull and honeycomb core structure. This enables high speed, high g-forced starts from ultrashort pneumatic launchers.

The world's first plasma flow controlled flying wing UAV has an improved performance at flight conditions which usually would stop other drones from flying because of strong crosswind induced flow separation and instability effects. The vehicles durability to crosswinds was increased by more than 60% and is thus higher than for other mini flying wing UAVs.
The high cruise speed and integrated plasma flow contol system makes the PlasmaFalcon system superior to existing flying wing drones. The sophisticated sliding discharge plasma actuators and generators were developed by our founder Berkant Göksel during his doctoral study at TU Berlin.

The 6 - 11 kg PLASMA FALCON 1.11 has a 2 - 4 kg payload volume (>33%), a powerful 1.0 (2.0) kW electric engine for fast (vertical) climbs after launch, a 360° ultrazoom visual systems with six 8K fisheye navigation cameras and one or two ultra light gyro-stabilized long range HD EO/IR cameras. An optional update kit was developed for hand-launched electric VTOL operations.

A subclass of the PLASMA FALCON 1.11 is the plasma flow controlled CoronaBat 1.11 which can be delivered from High-Altitude Platforms (HAPS) in a drag reducing swarm formation of four to six vehicles and glide for many hours when necessary.
For this purpose, the new vehicle uses the more powerful 384-core NVIDIA AI computer Jetson Xavier NX with six 220 degree fisheye navigation cameras based on Sony IMX 586 (686/786) image sensors with 48mp (64/108mp) to capture 360 degree videos with ultrazoom function.
A swarm of four vehicles with a three wingspan distance in diamond formation has about 50% less total drag. So all following vehicles have a longer range. By repeated change of the lead position the range of all vehicles can be similarly extended. In a V-type formation with three vehicles the overall drag reduces by 35% followed by an echelon formation with two vehicles with about 25% drag reduction.
Electrofluidsystems selected the world's most advanced mini dual electro-optical/infrared (EO-IR) stabilized NextVision cameras Colibri 2 and NightHawk2 for use in nose section and underbody.
There are four pre-serial prototypes for the PLASMA FALCON class with cruise speeds of 75-80 mph and a maximum flight endurance of 60-90 min. The 5.6 kg system has an endurance of 90 minutes and a range of 160 km (100 miles). The 6.6 kg version with the optional eVTOL update kit has an endurance of +60 minutes and a range of 100 km (75 miles) at 130 km/h (80 mph) cruise speeds. The next bigger version PLASMA FALCON 1.66 will use a 800 W fuel cell module from Intelligent Energy and have an extraordinary flight range of up to 330 km.

With CoronaBat UAS Electrofluidsystems redefines the next generation of swarm-capable, highly maneurable, high-speed mini UAV systems for real-time surveillance assisted by the AES-256 encrypted dual video telemetry system SmartLink Controller from our UK partner Sky-Drones Technologies. The SmartLink system will be also integrated in upcoming PLASMA RAY UAV systems.
The AI computer-based SWARMPILOT with six navigation cameras and the optional blockchain platform SWARMCHAIN will give us an additional customer benefit for more secure communication and coordination of swarming unmanned aerial vehicles (SUAVs).
Electrofluidsystems CoronaBat 1.11 with its huge payload bay is also a 1:20 (CoronaBat 22.2) and 1:27 (CoronaBat 30.0) scale model for a new generation of flying wing cargo aircrafts with ultra-efficient 550 PS RED AIRCRAFT A03 Diesel engines which can be also modified to work with hydrogen fuel using plasma combustion systems. The standard A03 high-altitude engine with 500 PS can provides 375 PS at 35,000 ft (10,668 m).
At 45,000 ft (13,716 m) altitude, the CoronaBat 22.2 needs 460 PS to fly with a speed of 400 km/h. Otto Aviation uses advanced multi-stage turbo chargers and heat exchangers in the Celera 500L to compensate the dramatic power drop at altitudes from 10,668 m to 15,000 m where the standard engine only provides 170 PS (see for the US patent 9,446,835 B2 from William Otto).
The payload bay of both versions can be easily accessed through the front door and in case of the bigger 8,600 kg variant with 30.0 m span can carry different standard cargo containers like LD-1, LD-2 or LD-3 and also different bulk cargo packages on 463L master pallets (HCU-6/E) as shown in the concept visualization above. The CoronaBat 30.0 will have a rear clamshell door to release airdrop pallets.
Electrofluidsystems optionally piloted flying wing cargo UAV CoronaBat 22.2 can also fly with sustainable aviation fuel-powered GE Catalyst turboprop engines and reach a constant cruise speed of 507 km/h (272 kts) at 13,176 m (45,000 ft) altitude. The same engine can also power the upscaled CoronaBat 30.0.
PLASMA (RAY) FLYER 1.11 / 11 - 18 kg MTOW
The stingray-shaped PLASMA RAY is an electric VTOL (eVTOL) UAV with 1.11 m wingspan and a maximum take-off weight (MTOW) of 11 - 18 kg. The deliverable payload weight is 4.0 - 8.2 kg. The near-term vision is to extend the product family to 1.66 m - 3.33 m wingspan until 2027. The AI swarm controller (SWARMPILOT) will enable coordinated flights in half-diamond and full diamond-shaped formations, reducing drag and increasing range by up to 50%.
The first pre-serial prototypes of the PlasmaRay with 1.11 m wingspan will use 12 electric ducted fan (EDF) jets from Schuebeler (DS-30-AXI HDS) and three kind of different brushless electric motors. There will be three basic versions for the PlasmaRay:

PLASMARAY 1.11 and H2PLASMARAY 1.11 UAV systems are plasma flow controlled, swarm capable eVTOL demonstrators for a new class of hydrogen fuel-cell powered, hyperfast air taxis with 6.66 m (900 - 1,000 kg), 8.88 m (1,850 - 2,000 kg), 11.1 (3,000 kg), 13.3 m (5,700 kg), 18.0 m (10,500 kg) and 19.9 m (13,500 kg) wingspan.
Electrofluidsystems also works on new heavy cargo BWB aircraft concepts based on the PlasmaRay design. A 4,700 kg PlasmaRay system would use 36 Vasyfan VF-570 lift fans (with each having 150 kg static thrust).
