B-Technology was founded in 2020 by Witold Mielniczek, Dawid Smolka and Vadym Melnyk in Poland. The company says it has made the first hybrid-electric vertical takeoff and landing (VTOL) and all terrain ground vehicle for advanced air mobility (AAM). called the Beccarii Carcopter. The company has international patents on its vehicle’s design. (All photos used with permission by B-Technology.)

GoAero competition
Mielniczek entered the GoAERO three year competition (2024-2027) offering over $2 million USD in prizes developed by Boeing, NASA and other organizations. For the GoAERO contest, Mielniczek came up with 60 different ideas before deciding on the XSERALL ATD air, land and water vehicle. The primary focus for the team is to provide a rapid response vehicle for natural disasters and medical emergencies in hard-to-access areas. The future goal for the company is to provide a well designed and manufactured vehicle for mobility, autonomy and accessibility in the most extreme environments.

Historical perspective
Mielniczek participated in the the DARPA UAVForge Challenge in 2012, where his team beat out more than 150 other competitors to capture First Place.

Beccarii XERALL ATD passenger hybrid-electric VTOL, land and underwater vehicle (prototype)
The Beccarii XERALL ATD is a one passenger hybrid-electric VTOL, land and underwater full-scale prototype vehicle. The company has made and is testing a subscale prototype proving the vehicle can take flight, travel by land (road and off-road), and traverse through and underwater. The company reveals the vehicle is for military applications. The ATD in the name translates to all-terrain drone.

The vehicle has a canopy over a sealed cockpit so the pilot can travel underwater and still breath. The vehicle has eight propellers, eight electric motors and is powered by a hybrid-electric power source. The vehicle has continuous track (track that is similar to tank track) for propulsion on land and through water. The propellers are concealed in the middle of the continuous track protecting the propellers during land and water travel. 

The fuselage is made from carbon fiber composite to give the aircraft a high strength to low weight ratio. The aircraft uses its continuous shock-absorbing track as landing gear. In the event of a hard landing or on uneven terrain the shock-absorbing suspension will significantly reduce damage or have no damage and be able to continue on its mission. 

To help raise money, the company made a small working drone called the X-Tankcopter with a similar design for children. 

About the GoAERO Prize Competition
The GoAERO Prize, sponsored by Boeing, is a three year competition (2024-2027) offering over $2 million USD in prizes that challenges engineers worldwide to create portable, versatile and autonomy-enabled Emergency Response Aircraft that address not only everyday medical emergencies but also to be used in natural disasters, humanitarian emergencies and climate crises worldwide. Each team designs and builds autonomous Emergency Response aircraft capable of delivering a first responder, medical equipment and supplies and ultimately evacuating victims in need to a rescue ambulance or hospital.

More than 150 teams from around the globe are competing for the GoAERO prizes. The GoFly and GoAERO prizes were developed by Boeing, NASA and other organizations to help the nascent advanced air mobility (AAM) industry move forward.

Specifications:

• Aircraft type: Passenger hybrid-electric VTOL, air and underwater vehicle.
• Piloting: Pilot
• Capacity: 1 pilot
• Cruise speed: Unknown
• Propellers: 8 propellers
• Electric motors: 8 electric motors
• Power source: Hybrid-electric power source
• Fuselage: Carbon fiber composite
• Window: Canopy over cockpit
• Landing gear: Continuous track for road, off-road and underwater travel and is also for landing gear
• Safety features: Distributed Electric Propulsion (DEP) uses multiple propellers or electric ducted fans, each powered by electric motors, to increase safety through redundancy. If one or more components fail, the remaining ones can still ensure a safe landing. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure. The aircraft has no moving surfaces or tilting parts when transitioning from vertical to forward flight and the reverse which increases safety by reducing complexity.
