Singapore is set to become the world’s first airport testbed for next-generation propulsion technologies, following a Memorandum of Understanding (MOU) signed by the Civil Aviation Authority of Singapore (CAAS), CFM International, and Airbus. The agreement, signed at the Changi Aviation Summit on 2 February 2026, focuses on testing CFM’s Revolutionary Innovation for Sustainable Engines (RISE) technologies, particularly the Open Fan engine architecture.
The collaboration aims to develop a comprehensive readiness framework for integrating Open Fan engines into existing airport operations. This includes considerations for aircraft system design, infrastructure modifications, operational procedures, safety standards, and regulatory measures. The framework will serve as a global blueprint for airframers, airports, and airlines.
The RISE programme, led by CFM, seeks to advance commercial aircraft engine technologies, promising over 20% better fuel efficiency than current engines. The Open Fan architecture, a key feature, is designed to reduce emissions and noise whilst being compatible with future hybrid-electric systems.
Operational trials of the Open Fan engine demonstrators are planned at Singapore Changi Airport or Seletar Airport to validate the framework and assess the technology’s feasibility. Han Kok Juan, Director-General of CAAS, highlighted Singapore’s role as an integrated air hub, stating that the partnership underscores the country’s regulatory expertise and capability to testbed new technologies.
Gaël Méheust, CEO of CFM International, emphasised the importance of real-world demonstrations to build confidence in the new technology’s safety and efficiency. Remi Maillard of Airbus expressed excitement about advancing propulsion technologies in Singapore’s state-of-the-art aerospace ecosystem.
