Product Background:
The CFM International RISE (“Revolutionary Innovation in Sustainable Engines”) is an open rotor engine currently under development by CFM International, a 50/50 joint venture between GE Aerospace (USA) and Safran Aero Engines (France). The engine is planned to support both hydrogen and sustainable aviation fuels and to reduce fuel consumption and CO2 emissions by 20 percent compared to its predecessor.

The 1973 oil crisis led to rising oil prices in the 1970s, prompting engine manufacturers to investigate new technologies to reduce fuel consumption, including open-rotor (also known as propeller-fan) engines. However, none of these designs were used in production airplanes, largely because of falling oil prices and concerns about the high noise levels of these engines.
In the years leading up to the announcement of the RISE program, both Safran and GE Aviation had experimented with open-rotor-based engine designs. Safran ground-tested an open-rotor engine in 2019 as part of the European Union's Clean Skies program, while GE conducted wind-tunnel tests on a derivative of the GE36 engine in the early 2010s in collaboration with the U.S. Federal Aviation Administration.

Program Announcement
CFM International announced the RISE program in June 2021 as the anticipated successor to the CFM LEAP turbofan engine, scheduled to enter service in the mid-2030s. At the 2022 Farnborough Airshow in July of the same year, CFM International and Airbus announced plans to begin flight testing of the RISE engine in 2026 on an Airbus A380-based test bed.

In June 2023, General Electric tested the first rotating components of the new engine, pairing the first stage of a high-speed, low-pressure turbine with the GE F110 military test engine. [9] As of late 2023, GE is producing test parts with the goal of producing a demonstrator engine for flight testing. The demo engine will pair an open fan set with a GE Passport gas generator.

1. Designed and licensed by Levihathan, the product is inspired by CFM's open rotor engine. Featuring wonderful detailing and beautiful design, the product continues the design thinking of the designer's previous LEAP's internals as the intended successor to the CFM LEAP turbofan engine. The product restores the single-stage open rotor in a traction configuration. The main bracket conceals the motor and working variable pitch mechanism. Excellent design, sturdy, both aesthetics, while fully taking into account the fun in the assembly, with a very high ornamental and collection value;

2, parts introduction: the use of environmentally friendly ABS material, contains a total of 1283 parts, and each part of extremely high quality, precision casting processing molding, matching degree is very high, tight not loose, solid shape, parts without burrs jagged, the overall smooth and smooth, the surface without scratches, splicing process is very safe;

3, the manual steps are clear: with QR code manual, need to scan through the cell phone camera to get the cloud manual data, the steps are detailed and easy to understand, according to the illustrated manual can be quickly assembled;

4、Block assembled is a good display model and background decoration; can exercise hands-on ability and thinking ability. It is the best gift for block novice, block collector, model airplane enthusiasts, block engine enthusiasts;

5, Note: There are small particles inside, pay attention to the use and placement, suitable for people over 16 years old; If you encounter any problems in the process of assembling, please contact us in time;
