Airbus PioneerLab Prepares For 2026 Critical Design Review

With Airbus Helicopters’ PioneerLab on track to make its first hybrid-electric powered flight in 2027, the project is looking to pass its Critical Design Review (CDR) in the middle of this year: building on a Preliminary Design Review (PDR) completed in 2025.

Flight testing – including new capability demonstrations - is expected to continue until around Q3, at which point the aircraft will enter a layup period to receive additional airframe modifications. Project manager Dominik Strobel told AIN that these upcoming “aerodynamic improvements” will be instantly recognizable across the airframe, although noted that these sequential modifications are the result of “really good planning.”

Other objectives of the ongoing flight test campaign include refining the PioneerLab’s automated takeoff and landing system. “Today, our helicopters are quite advanced. They can do quite a lot autonomously, but the final touchdown they cannot do,” explained Johannes Plaum, head of research and technology at Airbus Helicopters Germany.

A fully automated landing and takeoff was first performed last summer into Airbus Helicopters’ Donnauworth, Germany facility, combining a network of external cameras called Master360 with an automated path correction system. AI-enabled image recognition was further enhanced by a nose-mounted radar system and LiDAR scanning technology. During the fully automated landing, “the helicopter was capable of recognizing [a simulated obstacle], detect it, and then perform an avoidance manoeuvre before touching down,” explained Strobel. Up next, the team plans to replicate the feat into an unprepared site.

Upcoming design freeze

The upcoming CDR marks a significant milestone for the technology demonstrator, which Airbus intends to fly with an experimental hybridized powertrain next year. For this, the H145’s existing Safran Helicopter Engines Arriel 2E turboshafts will be replaced by a hybrid-electric system, combining a single Pratt & Whitney Canada PW210S engine with two Collins Aerospace 250-kW electric motors and controllers.

Accordingly, Plaum recognizes that the “impact on the helicopter is quite deep:” affecting avionics and electrical systems as well as powerplants themselves. The team’s completion of the PDR means it has now “assessed the impact on all the systems of the helicopter by the changes [it’s] going to introduce into the machine, and have frozen all the interface specifications,” he confirmed.

Although Strobel caveats that “there are a lot of dependencies with the partners we have” to achieve the 2027 timeline – with many partners and suppliers working across different sites – the team remains confident.  Airbus will initially look to validate the hybrid system’s functions before pursing quantifiable gains, with the hybrid-powered demonstrator to focus solely on this test mission following its installation.
