The Ancient Sling
The sling, an ancient weapon, has been around for thousands of years. It consists of a small cradle or pouch connected to two retention cords. A projectile is placed in the pouch, and the sling is swung in an arc. At the right moment, a tab is released, propelling the projectile towards the target. This ingenious device uses double-pendulum kinetics to throw stones or spears much farther than by hand alone.
Historical Significance
Slings have been found in archaeological sites dating back to around 2500 BC in Peru and 1200 BC in Nevada. The oldest known slings from the Old World were discovered in the tomb of Tutankhamun, who died around 1325 BC. These slings were likely used for hunting.
Centrifugal Force
The sling’s effectiveness lies in centrifugal force. When the sling is spun, this force keeps the projectile in the pouch. Upon release, the force propels the projectile forward. Centrifugal force is also used in everyday devices like washing machines and laboratory centrifuges.
Modern-Day SpinLaunch
In a modern twist, SpinLaunch has developed a system that uses centrifugal force to launch rockets. Their system spins a rocket inside a vacuum chamber until it reaches speeds over 7,200 feet per second, at which point it is released into the sky. This innovative approach aims to make space travel more cost-effective and sustainable.
Recent Developments
SpinLaunch has been making headlines with its suborbital test flights and partnerships with agencies like NASA. However, recent updates suggest that the company has faced challenges in progressing to their Orbital Accelerator system3. Despite these hurdles, SpinLaunch continues to work towards revolutionizing space travel with their high-tech slingshot technology.
