Traditional aircraft thermal management systems were designed for the predictable heat generation of turbofan engines and avionics. In contrast, integrating electric motors, batteries, fuel cells, and power electronics creates a thermal environment with variable heat loads and strict temperature requirements for optimal component performance and safety.
The scale of the challenge is stark: while current regional aircraft manage 35–50 kW of heat, hybrid-electric models must handle 300–1,000 kW. This increase is due to high-power electric motors, battery packs requiring precise temperature control, fuel cells generating substantial waste heat, and power electronics producing heat during energy conversion. Each subsystem has distinct thermal requirements, with batteries especially sensitive to overheating and cold, and fuel cells requiring stable temperatures for optimal electrochemical reactions.
Conflux’s additive manufacturing enables adaptive thermal management solutions, such as heat exchangers with geometry changes along the flow path to accommodate shifting fluid properties and temperature conditions. For example, in hydrogen fuel cell applications, internal geometry can be tailored to intensify heat transfer as air cools, a feat not possible with traditional manufacturing. TheMa4HERA will leverage comprehensive digital twin capabilities to simulate and optimize component-level requirements for any aircraft architecture, validated in full-scale test facilities at Fraunhofer IBP.

Collins Aerospace Begins Hybrid-Electric Powertrain Testing for Clean Aviation
Collins Aerospace initiates testing of hybrid-electric propulsion systems at The Grid lab for the EU Clean Aviation SWITCH project to reduce emissions and improve efficiency.
This article is based on an official press release from RTX / Collins Aerospace.
On March 16, 2026, Collins Aerospace, an RTX business, announced a major milestone in sustainable aviation by initiating testing for its electric motor drive systems. According to the official press release, this testing is a core component of the European Union’s Clean Aviation SWITCH project, which aims to revolutionize propulsion for future Commercial-Aircraft.
The testing is currently underway at “The Grid,” the company’s advanced electric power systems laboratory located in Rockford, Illinois. This phase marks a critical step in the development of hybrid-electric Propulsion technologies, which are designed to significantly reduce emissions and improve fuel efficiency for future short- and medium-range commercial aircraft.
As the aviation industry faces mounting pressure to decarbonize, hybrid-electric systems offer a viable near-to-medium-term solution. By transitioning from theoretical design to physical megawatt-class testing, Collins Aerospace and its European partners are moving hybrid-electric commercial flight closer to reality.
The current testing phase focuses on an integrated hybrid-electric powertrain subsystem. According to the company’s announcement, this subsystem includes two megawatt-class motor generators, advanced controllers, and comprehensive power distribution systems. Following successful validation, these key subsystems will be integrated into a hybrid-electric Pratt & Whitney GTF engine demonstrator for the next phase of testing.
“The Grid,” where these tests are being conducted, is a $50 million, 25,000-square-foot facility that officially opened in October 2023. Designed with an initial test capability of 8 megawatts, enough to power a small town, the lab allows engineers to evaluate full propulsion systems in real-world configurations rather than isolating individual components.
“The start of powertrain subsystem testing is a key step towards demonstrating the potential of applying more electric systems to future commercial aircraft. Hybrid-electric technology has the potential to transform aviation by enabling greater fuel efficiency across multiple future platforms, including next generation single-aisle aircraft.” The SWITCH project, standing for Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics, is a major initiative funded by the European Union under the Clean Aviation Joint Undertaking. The consortium is coordinated by MTU Aero Engines AG and includes major aerospace players such as Pratt & Whitney, Collins Aerospace, GKN Aerospace, Airbus, and various European research institutions.
The project’s primary objective is to develop a novel propulsion concept that merges hybrid-electric propulsion with Water-Enhanced Turbofan (WET) technology and Pratt & Whitney’s GTF engine architecture. The SWITCH powertrain is a testament to cross-border aerospace collaboration. Components were developed across multiple European research and development facilities before arriving in Illinois for testing. Collins Aerospace designed and produced the megawatt-class electric motors and controllers in Solihull, UK, while the power distribution components, including a solid-state power controller and distribution panel, were designed in Nördlingen, Germany. Additionally, GKN Aerospace developed and built the high-voltage electrical wiring interconnection system (EWIS) in Papendrecht, Netherlands.
The environmental targets for the SWITCH project are ambitious. The initiative aims to improve fuel burn and energy consumption by 20% while achieving a 50% reduction in the climate impact of both NOx emissions and contrails compared to current state-of-the-art engines. Furthermore, the technologies are being designed to be fully compatible with 100% drop-in Sustainable Aviation Fuel (SAF) and will be evaluated for future use with Hydrogen.
The Clean Aviation Joint Undertaking targets reducing CO2 emissions of short-to-medium-range aircraft by no less than 30%, and regional aircraft by 50%. While fully electric aircraft remain limited by battery weight and energy density, hybrid-electric systems optimize the performance of fuel-burning gas turbines during energy-intensive phases of flight, such as takeoff, significantly reducing overall fuel consumption.
We view the progression of the SWITCH project as a vital indicator of the aerospace sector’s pragmatic approach to decarbonization. By focusing on hybrid-electric architectures for single-aisle aircraft, RTX and its partners are acknowledging the current limitations of battery technology while still pushing for substantial, near-term efficiency gains. The integration of these systems into the proven GTF engine architecture suggests a clear pathway to commercialization, rather than a purely experimental endeavor. Furthermore, RTX’s broader strategy, which includes the hybrid-electric flight demonstrator for regional turboprops and the PioneerLab project, underscores a diversified, multi-platform commitment to electrification.
SWITCH (Sustainable Water-Injecting Turbofan Comprising Hybrid-Electrics) is an EU-funded initiative aiming to combine hybrid-electric propulsion with Water-Enhanced Turbofan technology to reduce aviation emissions.
Testing is taking place at “The Grid,” a $50 million, 8-megawatt advanced electric power systems laboratory located in Rockford, Illinois.
The project targets a 20% improvement in fuel burn and energy consumption, and a 50% reduction in the climate impact of NOx emissions and contrails compared to current engines.

This influx of capital, supported by 3M and other major aerospace players, is earmarked for the development of JetZero’s full-scale demonstrator prototype. The demonstrator is currently on track for its inaugural flight in 2027, a critical milestone that will validate the aerodynamic efficiency and manufacturing viability of the blended-wing design.
We note that the strategic backing of an established materials giant like 3M is a significant vote of confidence for JetZero. While blended-wing body concepts have been studied by NASA and the military for decades, we recognize that transitioning the design to the commercial market introduces complex certification and manufacturing hurdles. 3M’s expertise in structural assembly and thermal acoustics directly addresses some of the most challenging aspects of building a pressurized, passenger-carrying all-wing aircraft. If the 2027 demonstrator flight is successful, the Z4 could realistically target commercial entry into service in the early 2030s, offering airlines a step-change in operating economics.
A blended-wing body (BWB) aircraft integrates the fuselage and wings into a single, continuous aerodynamic shape, eliminating the traditional cylindrical tube. This design significantly reduces aerodynamic drag and increases lift, leading to lower fuel consumption.
According to JetZero and 3M, the Z4 is designed to deliver up to a 50% reduction in fuel consumption compared to conventional tube-and-wing commercial aircraft.
JetZero plans to fly a full-scale demonstrator prototype of the Z4 in 2027, with the goal of entering commercial service in the early 2030s. 3M is providing both financial investment (via JetZero’s Series B funding round) and material science expertise. This includes solutions for lightning protection, structural assembly, and thermal acoustics.
