The European Union Aviation Security Company (EASA) has at present opened a session paper for business suggestions on its strategy to certify eVTOL engines.
In keeping with the doc:
“EASA obtained purposes to certify, or to offer adviceon the certification of, propulsion methods that vary from single electrical engines to finish Electrical/Hybrid Propulsion Programs (EHPS) with or with out power storage system.
“In keeping with Regulation (EU) 2018/1139 Article 11, merchandise shall be issued with a kind certificates.
…The totally different requests obtained by EASA problem the boundaries of the above ‘engine’ definition, therefore opening the query of what parts could be included in a single engine kind certificates as a part of such product. Regulation (EU) 2018/1139 Article 11 states the next: ‘No separate kind certificates shall be required for the design of engines and propellers which have been licensed as a part of the design of an plane […]’. This provision is applied in Regulation (EU) No 748/2012 level 21.A.21 and supplies the likelihood to certify the propulsion system as a part of the plane.
“….In keeping with the prevailing regulatory framework, no less than two doable approaches to certify an EHPS have been recognized:
- Plane strategy: the EHPS is licensed as a part of an plane.
- Engine strategy: the EHPS is licensed as an engine product -by figuring out these parts and gear (of the EHPS) crucial for the functioning and management according to the ‘engine’ definition of CS-Definitions Modification .
“A propeller could obtain its personal kind certificates. The above-mentioned “engine strategy” supplies the pliability to incorporate within the scope of an engine TC some/all components of the EHPS, besides the propeller. Though flexibility on the certification strategy is out there to candidates, on the time of utility/preapplication, EASA could advise on what it considers to be essentially the most acceptable strategy, relying on the complexity of interfaces between merchandise and their components, and in addition primarily based on the extent of methods integrations, to mitigate the chance of dispute between the totally different design organisations concerning their respective tasks.”
