Founded on Nov. 19, 2018, Peravia (PERsonal AVIAtion) is an electric vertical takeoff and landing (eVTOL) Urban Air Mobility (UAM), cargo eVTOL and electric drone manufacturer, based in Poland. The key goal is to produce and sell simple and affordable eVTOL UAM aircraft to individuals, so that people can fly with independence from any type of infrastructure.

The company's number one priority for their aircraft is safety. The basis for their safety is distributed electric propulsion (DEP) and the use of batteries to power their aircraft. The cargo eVTOL aircraft named, UnitJoy, has 32 ducted fans and 32 electric motors, powered by batteries. Having these multiple ducted electric fans provide a high level of safety because if if three, four or more ducted electric fans fail or if several electric motors fail, the aircraft will still be able to fly and land safely. 

Simplicity is the key for the company's aircraft design. Their aircraft is without tilt rotors, tilt wings, dangerous propellers, complex joints or any moving parts. The way the aircraft is made is an extremely efficient design due to battery to electric motor direct power, very few moving parts, an aircraft that is light in weight, and it uses a computer to control and fly the aircraft safely. If several of the electric ducted fans or electric motors stop working the cargo aircraft can safely land itself without incident. 

Batteries powering an electric aircraft also provide another enormous safety factor over gasoline or turbine powered aircraft. Petroleum powered engines not only have many moving parts which can fail and cause a catastrophe but the liquid fuel can catch fire if the right conditions are present. With batteries, there are no moving parts to fail and batteries typically do not catch fire. Battery powered aircraft also have another advantage in efficiency. Power from the battery goes directly to the electric motors and a NASA study shows that electric motors are two to fours times as efficient than gasoline or turbine engine and electric aircraft can have between five to 10 times lower energy costs than petroleum powered aircraft.

The UnitJoy cargo eVTOL is flown autonomously and allows for a heavy cargo load of 200 kg (440 lbs) to be transported safely and efficiently by air travel. This aircraft is made for urban, suburban, rural or remote areas to have cargo sent to its destination fast and cheaply. The cargo drone consists of a cargo storage area, propulsion system and wings. Each part of the aircraft is independent and can be transported separately. Any damaged part of the aircraft can be quickly replaced by new modules. The main advantage of the electric cargo drone is its modularity enabling the production of identical elements in large quantities resulting in a relatively low price, high reliability and easy replacement. In addition to the UnitJoy, Peravia is also developing the AirBend.
