ZeroAvia – Dornier228 – First Flight

Does Anyone Remember Suckling Airways?

They started by flying a Dornier 228 between Ipswich and Manchester airports.

But look at this Dornier 228 in a short flight from Cotswold Airport in Gloucestershire.

This press release from ZeroAvia is entitled ZeroAvia Makes Aviation History, Flying World’s Largest Aircraft Powered With a Hydrogen-Electric Engine.

This paragraph describes the aircraft’s engines in this testbed configuration.

The twin-engine aircraft was retrofitted to incorporate ZeroAvia’s hydrogen-electric engine on its left wing, which then operated alongside a single Honeywell TPE-331 stock engine on the right. In this testing configuration, the hydrogen-electric powertrain comprises two fuel cell stacks, with lithium-ion battery packs providing peak power support during take-off and adding additional redundancy for safe testing. In this testbed configuration, hydrogen tanks and fuel cell power generation systems were housed inside the cabin. In a commercial configuration, external storage would be used and the seats restored.

As I suspect a Dornier 228 can fly on one Honeywell engine, this must be a very safe way to prove the concept of the hydrogen-electric powertrain.

This paragraph indicates their path to full certification and entry into service in 2025.

ZeroAvia will now work towards its certifiable configuration in order to deliver commercial routes using the technology by 2025. The Dornier 228 will conduct a series of test flights from Kemble and later demonstration flights from other airports. Almost exactly two years ago, ZeroAvia conducted the first of more than 30 flights of a six-seat Piper Malibu aircraft using a 250kW hydrogen-electric powertrain.

That is an ambitious date, but, they haven’t got to develop and certify a new airframe.

Monte To Purchase 100 FC Aircraft Drives From ZeroAvia

The title of this post, is the same as that of this article on electrive.com.

This is the first paragraph.

ZeroAvia and Monte Aircraft Leasing will jointly market hydrogen-powered aircraft to regional operators. Under an agreement now signed between the companies, Monte will purchase up to 100 ZA600 hydrogen-electric powertrains from ZeroAvia to be installed on existing and new 5- to 20-seat aircraft.

Monte look to be an interesting company from their web site, which has this title.

Supporting The Transition Of The Regional Aviation Industry To Net Zero Carbon Emissions

The business model appears to be a well-proven and it is not that far removed from the one, colleagues and myself used to sell the project management system; Artemis.

In our case we took proven Hewlett-Packard computers and and other hardware, added our Artemis software and a custom-made desk and leased the systems to those who wanted to do project management, with as much support as our clients required. Customers just had to supply operators, printer paper and a thirteen amp socket.

Finance was obtained by various innovative methods, often through a bank manager, who was a bit of a rogue. But he was a rogue, who was on the side of the angels.

Later he became a firm friend of mine, before he sadly died within a few days of my wife.

Monte Aircraft Leasing’s model would appear to take a proven aircraft like a Cessna Caravan, Dornier 228 or Dash 8, replace the turboprop engines with a zero-carbon powerplant and then lease the aircraft. Often this will just be an additional lease to the existing operator.

The great advantage of this approach, is that the reengined aircraft does not need to be fully re-certified. It can fly under a Supplemental Type Certificate, which is described like this in Wikipedia.

A supplemental type certificate (STC) is a civil aviation authority-approved major modification or repair to an existing type certified aircraft, engine or propeller. As it adds to the existing type certificate, it is deemed “supplemental”. In the United States issuance of such certificates is under the purview of the Federal Aviation Administration (FAA).

Monte seem to have found a good way to make money from going net-zero.
