The Lockheed X-17 was a three-stage solid-fuel research rocket to test the effects of high mach atmospheric reentry. The first stage of the X-17 carried the rocket to a height of 17 miles (27 km) before burning out. The rocket would then coast on momentum to about 100 miles (160 km) before nosing down for reentry. The second stage engine would then fire before jettisoning and igniting the third and final stage. On April 24, 1957, an X-17 reached a speed of 9,000 miles per hour (14,000 km/h) at Patrick AFB.[1] Ultimately the X-17 would be traveling towards Earth at up to Mach 14.5.
The rocket engine used by the rocket is called 1.5KS35000, a solid propellant rocket engine designed by Thiokol. It was used in at least 23 launches.[3][4]
Polaris FTV program
The X-17 was used as a test vehicle to test technology for the development of the UGM-27 Polaris missile in 1957–1958. During this testing, the rocket was called the Polaris Flight Test Vehicle, or Polaris FTV. The Polaris FTV-3 was a standard configuration X-17. The Polaris FTV-5 was a two-stage configuration using the same first stage, a Sergeant rocket, with a different second stage.[5]
