CityJumper was founded in 2018 by a group of engineers in Osijek, Croatia. The company has the goal of taking advantage of modern drone technology which can be scaled to passenger electric vertical takeoff and landing (eVTOL) aircraft, provide the world with emission free aircraft. The company knows it has been proven that making electric aircraft is relatively inexpensive when compared to the price of conventional aircraft and at the same time, electric aircraft increases the safety margin of the aircraft exponentially. This way, the company can make a product that will benefit people and the planet. CityJumper is currently seeking investors to help make their clean eVTOL aircraft a reality.

CityJumper's Timeline of Events and Goals

• January 2019: A ⅐ scale model was made and tested
• February 2019: Patent registration of a 4+4 propulsion system with overlapping propellers has begun
• During 2019: Further development of the project, selection of excellent component suppliers
• February 2020: Granted international industrial design protection of CityJumper
• 2023: Begin test flights of the full scale production prototype
• 2025: Begin the production and the commercial use of CityJumper eVTOL aircraft

The two passenger CityJumper combination ground vehicle and eVTOL aircraft uses eight propellers and eight electric motors for urban flight and has four standard car wheels for road travel. Because the vehicle is both a car and eVTOL aircraft, this design will be an extremely useful and practicable vehicle for Urban Air Mobility (UAM) due the the lack of physical infrastructure it needs for urban flight. Gull-wing doors provide easy entry and exit of the vehicle.

The vehicle has a 400 km (248 miles) range and a flight time of 30 minutes, allowing its passengers to fly over rush hour traffic jams and reach the passenger's destination in very little time. The aircraft has the convenience of being piloted with the assistance of its navigation computers or the passengers can choose the flight to be flown autonomously. The aircraft has two lidar sensors and four radar sensors allowing it to navigate safely throughout any urban or rural area with a detect and avoid feature built into the computers.

CityJumper also has many safety features including Distributed Electric Propulsion (DEP) which means the aircraft uses multiple propellers for redundancy allowing the aircraft to still fly and land safely, even if one, two or three propellers fail during flight. The propellers are housed inside the frame of the car keeping ground crew members and passengers safe during take offs and landings. When the vehicle is not flying, there are retractable covers that close over the propellers.

The aircraft also has a whole aircraft ballistic parachute in case an emergency situation happens. There are six airbags inside the cockpit and there are four external airbags. Another safety feature of the aircraft is that it can land on the water using its outside airbags. The size of the vehicle allows the owner to park the car in a standard parking space or garage.

CityJumper is expected to be used for personal travel, corporate travel, on-demand Urban Air Mobility (air taxi service), tourism, natural disasters, medevac missions, fire fighting and police work.

Specifications:

• Aircraft type: eVTOL aircraft and electric ground vehicle
• Piloting: Assisted piloting or autonomous
• Capacity: 2 passengers
• Range: 60 km
• Road range: 400 km (248 miles)
• Flight Time: 30 minutes
• Propellers: 8 propellers
• Electric Motors: 8 electric motors
• Power source: Batteries
• Fuselage: Aluminum carbon fiber composite chassis, carbon fiber composite shell
• Dimensions 496 cm X 195 cm X 164 cm (16.27 ft X 6.4 ft X 5.38 ft)
• Doors: Gull-wing doors
• Windows: Has car-type windows
• Landing gear: 4 road wheels
• Safety features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers (or ducted fans) and motors on the aircraft so if one or more propellers (ducted fans) or motors fail, the other working propellers (or ducted fans) and motors can safely land the aircraft. The car can land on water using outside airbags. The flying car has a whole vehicle ballistic parachute. The propellers are housed inside the frame of the car keep crew and passengers safe during take offs and landings. When the vehicle is not flying, there are covers that close over the propellers. There are six airbags inside the aircraft and there are four external airbags.
