Honeywell has signed a memorandum of understanding (MoU) with India-based aeronautics company Hindustan Aeronautics Limited (HAL) to jointly manufacture high-power, high-voltage turbogenerators.

Honeywell will provide its one megawatt electric machine to be utilised as a generator that enables a turbogenerator to power hybrid-electric aircraft, including traditional airframes, unmanned aircraft and urban air mobility vehicles. This generator, which can also efficiently run as a one megawatt motor, can be seamlessly integrated with new and existing gas turbine engines to create highly power-dense turbogenerators.

Honeywell India president Rajesh Rege says: “In continuance with our commitment to deliver world-class, industry-leading technologies to India, we are delighted to partner with HAL once again. This MoU builds on a four decade-long partnership with the country's aeronautics leader and is an affirmation of our Make in India vision.”

HAL managing director and former chairman R Madhavan adds: “This MoU is intended to allow both parties to jointly develop a business plan which outlines the market potential, investment, returns and partnership model. Once the business plan's viability is established, we will enter into contract arrangements. Going ahead, we hope to work with Honeywell to develop a number of new, India-specific applications.”

Traditionally, aircraft use fuel-burning engines to mechanically turn rotors, propellers or fans. However, many new designs use a distributed electric propulsion architecture, in which many electric motors can be tilted or turned off for vertical take off and horizontal flight. A Honeywell turbogenerator can provide electric power for multiple electric motors anywhere on an aircraft.

It is capable of running on aviation biofuel, including green jet fuel as well as conventional jet fuel and diesel. It can be used to operate high-power electric motors, charge batteries and can satisfy missions from heavy-lift cargo drones to air taxis or commuter aircraft.

The MoU was exchanged between Honeywell Defense & Space senior director OE sales Eric Walters and HAL executive director (E & IMGT) B Krishna Kumar in the presence of R Madhavan and HAL CEO (BC) MK Mishra.
