Interesting Engineering is a cutting edge, leading community designed for all lovers of engineering, technology and science.
The system consists of a network of tiny channels embedded in the leading edges of the hypersonic vehicle, which are the parts that face the most heat.
Imagine flying faster than five times the speed of sound and reaching any destination in the world in hours. This is the vision ofHowever, achieving this feat is not easy, as it involves overcoming extreme temperatures of over 2,200 °C that can melt or damage most materials. The phenomenon called 'ablation' deforms any vehicle's angular shape post the speed of Mach 5 due to intense heat, which affects the overall performance of the vehicle and efficiency.
John Sharon, the center's project team leader, said that they used predictive modeling and advanced micro-machining to create a test article that resembled a credit card with a wedge shape. They then exposed it to two different heat sources: a burner rig that was like a giant crème brûlée torch and an electrical arc that simulated the conditions of hypersonic flight.
