First, the cosmic velocity is divided into two different names: the minimum launch speed of spacecraft and the maximum operating speed of spacecraft. In some cases, when a spacecraft operates at the first cosmic speed, it indicates that the spacecraft operates along the earth's surface. V1=7.9 km/s can be calculated according to the mechanics theory.
The author's speed test
At 27811 Ying Chi (Ying Chi) = 8476.7928 m (m), the speed of the aircraft can reach 12103mph.And that's the speed of 15.7 Maher
When the aircraft is at 46541 feet (FT) =14185.6968 m (m), the speed of the aircraft reaches 7.8km/s, the first cosmic speed.It's about 23 Maher
When the plane was 27516 feet (FT) =8386.8768 m (m), I tested the fastest 20000mph.And that's 26.29 Maher
The speed at this time is very amazing at 20000 miles / hour (mile/h) =8940.8 M / S (m/s), about 9km/s
