Benefits:The project will contribute to the development of the Fast Rotorcraft, a new configuration of helicopter that will enable fast and efficient forward flight while enabling vertical take-off and landing. Achieving the best trade-off between speed, cost-efficiency, sustainability and mission performance, the RACER will benefit missions for which travel time is of vital importance (such as search and rescue and emergency medical transport) also contributing to mission efficiency (such as inter-city urban air mobility) and low-noise flight procedures. ANGELA project will develop the landing gear system for RACER. It is composed by tricycle retractable left and right Main landing Gear legs, Nose landing Gear leg and the related compartment doors.
Keywords: Compound helicopter, landing gears
Duration:2016 – 2021
Budget:Circa 6 M€
Contract number:Grant Agreement number: 945542 — GAM-2020-FRC — H2020-IBA-CS2-GAMS-2019/H2020-IBA-CS2-GAMS-2019. Amendment Reference No AMD-945542-5



ANGELA project is funded by the European Commission through the Clean Sky 2 Joint Undertaking. The consortium is composed of five partners: the Italian Aerospace Research Center (Coordinator), the company Magnaghi Group, the SMEs Techno System Developments, M&S Engineering and Centre Composite, with AVIATEST as third party.

ANGELA project is aimed at designing, manufacturing, qualifying and flight-testing an innovative landing gear to be integrated on the RACER compound Technology Demonstrator, planned to be flying in 2022 (

The shipsets ANGELA consortium is developing for the Work Area Leader (Airbus Helicopters) are made of the following systems and sub-systems:

  • A Nose Landing Gear with retraction actuator and center lock mechanism
  • Two Main Landing Gears with retraction actuators
  • A Wheel (rims and tires) for each Main Landing Gear
  • Two Wheels (rims and tires) for the Nose Landing Gear
  • A Hydraulic brake on each main landing gear (brake control out of the scope)
  • Landing gear compartment doors and associated mechanism to open/close them for each Main Landing Gear and for the Nose Landing Gear.

Moreover, ANGELA is greatly focussed on developing specific innovative technologies with the ambition to go beyond the current state of art developing:

  • Hydraulic retraction systems with Innovative flush doors to reduce drag during high speed missions
  • Full electric retraction/extension system to achieve TRL5

Smart Landing Gear for Hard Landing Detection based on FBG (Fiber Bragg Grating) sensor network to achieve TRL5 demonstration.
