Kholod

Prototype of the Kholod rocket

Kholod (Холод) is the name of a rocket project. This project was developed in Russia. The engine of the rocket is called a scramjet. It was created to be faster than Mach 5.75. The prototype includes a Soyuz TMKB with liquid hydrogen and modified fillings from the SA-5 Gammon rockets. The rocket with the starting blocks (complete laboratory) is 12 meters long and has 750mm in diameter.[1][2] NASA cooperated on the fourth flight in February 12, 1998. The speed of that flight was Mach 6.4. 95 million United States dollars were invested in this project.[3][4][5]
