Lufthansa Technik's Lego CFM Leap-1B was under construction for nearly six months.
ATLANTA—A CFM Leap-1B engine made out of Lego bricks is making its worldwide public debut on April 18 at Lufthansa Technik’s booth (#1421) at MRO Americas.
The engine, built at 60% of the powerplant's actual size, is made of some 400,000 Lego pieces and weighs 450 kg (992 lb.). It measures 105.6 cm by 1.88 cm by 145 cm.
The idea came from a Lufthansa Technik employee who likes to build things out of Lego and his son, “who built the first Lego engines at a smaller scale for giveaways,” says Derrick Siebert, Lufthansa Technik’s VP of commercial engine services. “These were very well received from customers, and that is where the idea generated,” he adds.
Lufthansa Technik hired an outside company to assist for the Lego Leap-1B. “As there is no publicly available 3D model yet, the Lego model was created based on illustrations with the support of our engineers,” says a Lufthansa Technik spokeswoman.
The outside company started building the Leap-1B in October and finished it nearly six months later.
“It was great fun to see that growing from an idea from one of our employees to something that is creating so much positive feedback and curiosity for the topic,” Siebert says.
The actual CFM Leap-1B engine powers the Boeing 737 MAX family, providing 23,000-28,000-lb. thrust.
