🚀 Why do hypersonic vehicles have blunt noses?

At hypersonic speeds (Mach 5+), the biggest threat isn’t friction — it’s shock heating.

A sharp nose forces air to compress right on the surface, creating extreme temperatures that can melt materials.

A blunt nose pushes the shockwave away from the vehicle, forming a cushion of super-hot air in front of it.
That gap reduces how much heat actually reaches the structure.

Counterintuitive, but true:
🔺 Sharper = hotter
🔵 Blunter = cooler

This is why capsules like Apollo, Orion, and many hypersonic test vehicles look more like flying bricks than darts.

Physics beats aesthetics every time.

💬 Would you expect sharp or blunt to be better before reading this?
