TRANSFORMING AN EXISTING DESIGN WITH THE MANUFACTURER‍



BRM AERO

H55 first EPS 100 kW customer application is the Bristell B23 Energic, a
2-seater electric trainer designed for flight schools and pilot training.
Responding to the market demand for a 850KG CS 23 certified aircraft which can
take a pilot through most of the PPL training syllabus, the B23 Energic will be
commercially available in 2024.
‍
BRM is a Czech aircraft manufacturer established in 2009. With 5 models
available, BRM produces more than 100 aircrafts yearly. BRM AERO’s priority is
its emphasis on innovation, continuously introducing new developments to its
product line. With the B23 Energic, BRM positions itself as a pioneer of the
next aviation revolution.

HARBOUR AIR

H55 has been selected by Harbour air to provide the energy storage system for
the first commercial electric version of the Beaver commuter seaplane. H55
lightweight battery modules will be part of an electric propulsion system
whereby the US based magniX will be providing the motor. Once the 1st prototype
is certified, Harbour Air plans to first retrofit their entire fleet and then
offer the possibility to other Beaver owners the possibility to convert their
aircraft to electric.

Harbour Air, North America's largest seaplane airline —and the first to be fully
carbon-neutral offers flight services around the island of Vancouver, BC,
Canada. With short flights, no longer than 30-45 min, their airline service is
the perfect application for electric aircrafts and becoming the first airline
operating electric airplanes.

DEVELOPING AN HYBRID-ELECTRIC FLIGHT DEMONSTRATOR



PRATT & WHITNEY CANADA

Pratt & Whitney Canada (P&WC) has selected H55 to provide the battery pack for
the company’s regional hybrid-electric flight demonstrator program. The program
is supported by the Government of Quebec and Canada towards developing
sustainable propulsion technology. Collins Aerospace and De Havilland Aircraft
of Canada are key technology collaborators in the demonstrator project. The
National Research Council Canada (NRC) and the Innovative Vehicle Institute
(IVI) are also supporting the development of some of the component designs and
electrical control systems for the project. A 30% improvement in fuel efficiency
and commensurate reduction in CO2 emissions is targeted, compared to today’s
most advanced turboprop engines for regional aircraft. Ground testing of the
propulsion technology will already start this year, with a planned flight
demonstration in 2024.

in-service Piper Archer ® (PA-28-181) aircraft and bring an electric variant of
the aircraft to market as a Supplemental Type Certificate (STC). H55 has
committed to designing and manufacturing the aircraft battery system to support
CAE in the conversion of two-thirds of its Piper Archer ® training fleet with
electric propulsion and make the conversion kit available to all operators of
the aircraft type.

CAE is a high technology company and leading aviation training organization. The
company offers training and operational support solutions in civil aviation,
defense and security, and healthcare. CAE is also the biggest flight school
operating a fleet of Piper Archer.
