Kinetic space launch refers to a launch in which the vehicle is imparted very high initial velocity and leaves the launch apparatus at maximum speed. The vehicle, at least initially, is a simple projectile.
The highest velocity occurs at exit where atmospheric pressure is highest. Therefore
The dynamic pressure on the vehicle is highest.
Atmospheric drag is highest.
Aero-thermal effects are highest.
Currently, no one pursuing kinetic launch systems expects to reach orbit directly with a kinetic system. Rather, a second stage rocket will be used to attain the final increment of orbital speed. Companies do, however, expect to exceed the Karman Line. The Karman Line is the most commonly used definition of the threshold of space. It is 100 km Continue reading “Kinetic Space Launch”
‘More evidence that Hurricane Michael was definitely NOT a Category FIVE storm at landfall.’
Robert W. Endlich
In late September 2022 Category Four Hurricane Ian struck southwest Florida bringing death and destruction to southwest Florida. Ian’s arrival and wind damage spurred me to take another look at when 2018’s Hurricane Michael struck the Panhandle of Florida, and NOAA’s 2019 declaration that Michael was a Category Five storm at landfall.
