Product Background:The CFM International RISE ("Revolutionary Innovation for Sustainable Engines") is an open rotor engine currently under development by CFM International, a 50/50 joint venture between GE Aerospace of the United States and Safran Aircraft Engines of France. The engine is planned to operate on both hydrogen and sustainable aviation fuels and is projected to reduce fuel consumption and CO2 emissions by 20% compared to its predecessor.
The 1973 oil crisis led to rising oil prices in the 1970s, prompting engine manufacturers to research new technologies to reduce fuel consumption, including open rotor (also known as propfan) engines. However, none of these designs were adopted into production aircraft, primarily due to falling oil prices and concerns about the engines' high noise levels.
In the years before the RISE project was announced, both Safran and GE Aviation had experimented with open rotor-based engine designs. Safran conducted ground testing of an open rotor engine in 2019 as part of the EU Clean Sky project, while GE conducted wind tunnel testing of a derivative of the GE36 engine in the early 2010s in collaboration with the U.S. Federal Aviation Administration.
Program Announcement
In June 2021, CFM International announced the RISE program, a prospective successor to the CFM LEAP turbofan engine, scheduled for entry into service in the mid-2030s. At the 2022 Farnborough Airshow in July of that year, CFM International and Airbus announced plans to begin flight testing of the RISE engine on an Airbus A380-based testbed in 2026.
In June 2023, GE tested the first rotating components of the new engine, pairing the first-stage high-speed, low-pressure turbine with a GE F110 military test engine. By the end of 2023, GE was producing test components with the goal of producing a demonstrator engine for flight testing. The demonstrator will pair an open fan assembly with a GE Passport gas generator.
1. Product Description: Designed and licensed by Levihathan, this product draws inspiration from CFM's open rotor engines. Featuring exquisite detail and a refined design, it continues the designer's previous LEAP internal structure design philosophy, serving as the anticipated successor to the CFM LEAP turbofan engine. The product features a single-stage open rotor in a trailing configuration. The main support conceals the motor and the variable pitch mechanism. The design is excellent, sturdy, and aesthetically pleasing, while also taking into account the fun of assembling. It boasts both high ornamental value and collectible value.
2. Parts: Made of environmentally friendly ABS material, this set contains 1,351 high-quality parts. Precision casting ensures a precise fit, a tight fit, and a stable shape. The parts are free of burrs or jagged edges, resulting in a smooth, smooth, and scratch-free surface, ensuring a safe assembly process.
3. Clear Instructions: The set includes a QR code that can be scanned with your phone's camera to access the cloud-based instructions. The instructions are detailed and easy to follow, allowing for quick assembly according to the illustrated instructions.
4. Once assembled, the blocks make excellent display models and background decorations, enhancing both hands-on skills and thinking skills. It's a perfect gift for beginners, block collectors, model aircraft enthusiasts, and block engine enthusiasts.
