Designed and licensed by Levihathan, this product draws inspiration from CFM's open-rotor engine. It features intricate details and exquisite design, continuing the design philosophy of the LEAP's internal structure, which served as the anticipated successor to the CFM LEAP turbofan engine.The product faithfully reproduces a single-stage open-rotor with a pull configuration.
CFM International's RISE ("Revolutionary Innovation for Sustainable Engines") is an open-rotor engine currently under development by CFM International, a 50/50 joint venture between the American company GE Aerospace and the French company Safran Aircraft Engines. This engine is designed to support both hydrogen fuel and sustainable aviation fuel, aiming to reduce fuel consumption and CO2 emissions by 20% compared to its predecessor.
The 1973 oil crisis led to increased oil prices in the 1970s, prompting engine manufacturers to explore new technologies to reduce fuel consumption, including open-rotor (also known as propfan) engines. However, these designs were not adopted for production aircraft, primarily due to falling oil prices and concerns over the high noise levels of these engines. In the years preceding the RISE project announcement, both Safran and GE Aerospace had experimented with open-rotor engine designs. As part of the EU Clean Sky project, Safran conducted ground tests of an open-rotor engine in 2019, while GE collaborated with the US Federal Aviation Administration in the early 2010s to perform wind tunnel tests on a derivative of the GE36 engine.
