Lufthansa Technik makes use of Ansys’ simulation options to create and validate an plane coating expertise impressed by shark pores and skin that considerably reduces drag, gasoline consumption, and CO₂ emissions

/ Key Highlights

• Lufthansa Technik integrates Ansys’ simulation options to develop and confirm AeroSHARK, an revolutionary plane coating expertise that imitates the traits of shark pores and skin to cut back plane drag and friction
• By simulating all the plane utilizing Ansys software program, Lufthansa Technik was capable of de-risk the expertise for flight testing and drastically cut back time to certification

PITTSBURGH, June 6, 2023 /PRNewswire/ — Lufthansa Technik, one of many world’s main suppliers of technical plane providers, integrates Ansys’ (NASDAQ: ANSS) simulation options to design and certify AeroSHARK, a biomimetic coating expertise that emulates shark pores and skin and considerably reduces gasoline consumption and carbon dioxide (CO₂) emissions.

By leveraging Ansys’ computational fluid dynamics (CFD) and high-performance computing (HPC) expertise, Lufthansa Technik and BASF, a chemical firm, designed the coating movie with a delicate ribbed texture consisting of small elevations known as riblets. The riblet impact imitates the placoid scales on shark pores and skin, which assist sharks reduce by means of water effortlessly by lowering drag and friction whereas growing buoyancy. Engineers used Ansys’ CFD to research turbulent circulate phenomena surrounding the riblets to make sure they might generate the identical impact.

Lufthansa Technik used Ansys’ instruments to construct and validate smaller, extra generic digital prototypes of AeroSHARK earlier than scaling and tailoring the prototypes by means of complete aerodynamic simulations. With the flexibility to simulate all the plane, together with in-flight conduct, and confirm the riblet impact utilizing revolutionary turbulence modeling, Lufthansa Technik lowered the chance of bodily flight exams and drastically lowered the time to certification.

AeroSHARK is licensed by the European Union Aviation Safety Agency (EASA) and the American Federal Aviation Authority (FAA) for 2 forms of Boeing 777s and is presently working in flight by Swiss International Air Lines (SWISS) and Lufthansa Cargo. Once all eleven Boeing 777Fs at Lufthansa Cargo and all twelve 777-300ERs at SWISS have acquired their AeroSHARK modification, they’ll cut back the Lufthansa Group’s carbon footprint by greater than 25,000 tons yearly.

“AeroSHARK can significantly contribute to more sustainable air transport,” mentioned Stefan Kuntzagk, senior engineer, plane efficiency, CFD, and flight take a look at at Lufthansa Technik. “With the ability to model aircraft and aerodynamic behavior in a predictively accurate, robust, and computationally efficient manner by using Ansys’ simulation solutions, we can enhance and expand our shark-inspired technology to make entire subfleets more climate-friendly, reduce fuel consumption, and decrease CO₂ emissions for commercial aircraft.”

Today, due to profitable simulation-powered testing, 40% of the plane can already be coated by AeroSHARK with plans to increase its protection to different areas of the aircraft.

“We are constantly amazed by the creativity of our customers, and Lufthansa Technik has elicited the same reaction with its trailblazing AeroSHARK coating technology, which has the potential to significantly reduce fuel consumption and CO₂ emissions,” mentioned Walt Hearn, senior vp of worldwide gross sales and buyer excellence at Ansys. “Our customers continue to demonstrate what is possible when Ansys’ simulation solutions are combined with ingenuity and vision. As more sustainable propulsion systems are still being researched and tested, innovations like AeroSHARK are pivotal in the immediate reduction of aviation’s carbon footprint.”
