P&WC outlines hybrid PW127 for ATR Evo as Collins partners and H55 advances 200 kWh battery demonstrator

RTX says Pratt & Whitney Canada is developing an advanced hybrid‑electric PW127 turboprop under an EU Clean Aviation project that could power ATR’s Evo. P&WC and Collins Aerospace are co‑designing the hybrid propulsion system, and Swiss firm H55 reports flight‑tested progress on a 200 kWh battery for demonstrators.

Briefing

What Hype is tracking

The propulsion work could determine ATR’s Evo feasibility and commercial case ahead of its end‑2029 go/no‑go decision; the programme ties directly into ATR’s planned development timetable and investment commitments (see ATR’s 2029 decision context) (source:84b0b638) and ATR’s major investment push (source:2e13c223).
H55’s reported, flight‑tested 200 kWh battery targets up to 30% fuel‑burn reduction on hybrid demonstrators, a material metric for OPEX and emissions outcomes on regional turboprops described in the cluster sources.
The effort leverages broader P&WC hybrid demonstrators and RTX/Collins industrial links—strengthening supply‑chain and capability commitments that follow RTX’s recent regional investment and P&WC hybrid programme activity (source:ad9c11e4) (source:1769c2eb).
