Hypersonic planes that promise to fly from Sydney to London in four hours are a step closer to reality after a technological breakthrough.
UK-based Reaction Engines has announced its engineers have successfully tested a pre-cooling system that enables engines to survive Mach 5 speeds – or 6,400 kms/ph.
The engine works by rapidly chilling the incoming air to zero using tiny tubes of cooled helium. Captured heat also powers the engine.
Helium One is an independent specialist explorer focussed on delineating and developing globally significant helium assets in Tanzania, Solo Oil PLC (LON:SOLO) has a 15% equity in the company.
