On January 19, ZeroAvia, a hydrogen-powered aircraft manufacturer, made history by successfully completing the first flight of a real airliner powered by an electric hydrogen engine. The aircraft, a modified 19-seater Dornier 228, completed a six-minute lap around the track during take-off from ZeroAvia’s research and development facilities at Cotswold Airport in Gloucestershire, UK.

This milestone marks a significant step forward for ZeroAvia and the future of hydrogen-powered aviation. The Dornier 228 used in the flight was not the company’s highly-anticipated Celera 500L, but it was still a significant achievement for the company. The prototype of ZeroAvia’s 600 kW hydrogen electric motor was placed under the aircraft’s left wing, making it the manufacturer’s largest engine to ever be tested in flight.

For safety reasons, the original internal combustion engine, a Honeywell TPE-331, was retained on the right wing. The hydrogen engine was powered by two fuel cells and lithium-ion batteries, which guaranteed full power during take-off and served as a backup in case of failure. The power supply system was located inside the cabin, but in the final version, it will be placed outside.

This achievement demonstrates the potential for hydrogen-powered aviation and the advancements being made in sustainable transportation. As the industry continues to research and develop hydrogen fuel cell technology, we may see more of these types of aircraft in the future.

ZeroAvia aims for 90-seat hydrogen-powered planes by 2025

ZeroAvia, a hydrogen-powered aircraft manufacturer, made a significant advancement in sustainable transportation by successfully completing the first flight of a real airliner powered by an electric hydrogen engine. This flight was part of the HyFlyer II project, which aims to develop a hydrogen engine for aircraft with a capacity of 9 to 19 passengers. With this important step, the company is planning to apply for certification as early as this year.

The flight was carried out with the agreement of the British regulatory body, the Civil Aviation Authority (CAA), whose requirements exceeded those of typical flight tests. This provided a significant margin for development for the engine manufacturer. ZeroAvia is now considering commercial certification by 2025.

In the future, ZeroAvia plans to design 2 to 5 MW engines that can propel commercial aircraft with a capacity of 90 passengers on a range of over 1,100 km. To achieve this goal, the company is supported by industry players and airlines such as United Airlines. This achievement demonstrates the potential for hydrogen-powered aviation and the advancements being made in sustainable transportation.

The company’s next goal is to develop a larger hydrogen-powered engine to power commercial aircraft, which is a significant step towards a cleaner and greener future in the aviation industry.


Revolutionary hydrogen-powered aircraft takes flight towards eco-efficiency

Otto Aviation, the manufacturer of the Celera 500L, has partnered with hydrogen-powered aircraft manufacturer ZeroAvia to develop a version of the aircraft equipped with a hydrogen fuel cell powertrain. This new aircraft will be able to carry 6 to 19 passengers over a distance of 1,852 kilometers.

The Celera 500L boasts a unique and counter-intuitive design, with wings resembling those of a glider. This design allows for a reduction in drag by almost 60%, thanks to the rounded shape of the cabin which optimizes laminar flow, reducing the mixing of layers of air and ultimately resulting in lower drag and energy consumption.

This efficiency is reflected in the cost of operation, which is projected to be five to seven times less than a business jet, with a reduction of 80% in fuel consumption. Currently, the aircraft is only in the prototype stage and powered by a 500-horsepower combustion engine, but with the switch to hydrogen power, it is expected to be even more economical in the future. The next step in the development of the Celera 500L is to incorporate hydrogen fuel cells, and Otto Aviation has joined forces with ZeroAvia to make this a reality. The partners believe that with this hydrogen fuel cell powertrain, the aircraft will have a range of 1,852 kilometers.

Otto Aviation & ZeroAvia partner to create more sustainable business aviation

The Celera 500L, manufactured by Otto Aviation, is a unique aircraft that boasts impressive finesse thanks to its shape and wings, despite its overweight. It’s capable of carrying up to six passengers over a distance of 8,335 kilometers at a cruising speed that is higher by about 740 km/h. The manufacturer estimates that it could offer a model that can accommodate up to 19 passengers, but this would be the maximum due to the proportions of the aircraft.

During the 55 successful test flights, the Celera 500L has been able to operate at speeds greater than 400 km/h and a maximum altitude of 5,000 meters. It also has the capability of traveling up to 200 kilometers in gliding flight with the engine off from its cruising altitude.

Whether it retains its propulsion with fossil energy or switches to hydrogen, the aircraft will significantly reduce the carbon footprint of private business aviation. This is a big step towards sustainable transportation, and the company is working on making this a reality. The Celera 500L is a proof of effectiveness of the design and shape of the aircraft, which is able to reduce drag and optimize laminar flow, resulting in lower energy consumption and ultimately reducing the environmental impact.


Revolutionary experimental plane aims to revolutionize tourism transport

The Celera 500L, designed by Otto Aviation, is an experimental aircraft that boasts exceptional performance and efficiency. Its unique shape and slender look, reminiscent of an airship, sets it apart from traditional passenger aircrafts. It has already completed 31 test flights and has the potential to revolutionize the transportation industry.

The Celera 500L is powered by a V12 Diesel engine, delivering 500 horsepower which is rare for a passenger aircraft, and is found on a few aircraft, including the Yak-52 and spreading plane. With this engine, the single-engine aircraft will be able to reach a maximum cruising speed of over 724 km/h and a range of 8,330 kilometers.

According to the aircraft manufacturer, the fuel economy of the Celera 500L would be eight times greater than that of an equivalent business jet, and it will be able to reduce emissions by 80%. The Celera 500L is designed to carry six passengers and it’s a promising step towards sustainable transportation.

Revolutionary design optimizes laminar flow for fuel efficiency

The Celera 500L, manufactured by Otto Aviation, is designed to reduce its carbon footprint and increase efficiency by optimizing the flow of air around the cabin, wings and tail (empennage). This is achieved by improving the laminar flow on the fuselage.

The aircraft’s aerodynamics allow for the air to slide as slowly as possible over the surface, preventing different layers of air from mixing and creating drag. The aircraft’s unique elongated ovoid shape, combined with long, thin and narrow wings, reduces drag by up to 59%, resulting in a significant improvement in lift. This leads to 80% less carbon emissions compared to an equivalent business jet.

The Celera 500L has the capacity to carry six passengers in a 1.85 meter high cabin and is expected to enter service in 2025, after gaining certification from the American authorities scheduled for 2023.
