Natural Terrestrial Environment from Selected Field Data Measurements: Results and Applications for Launch Vehicle Development

Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT:

This paper is mainly a review presenting 3 unique NASA natural environment field projects. Included are some important natural environment technical results and applications that are applicable in the design, development and operations of launch vehicles as well as in advancing the atmospheric state-of-the-art. For the design, development, testing, launch and flight of various launch vehicles all natural terrestrial environments are considered, with normally wind being the main contributor or driver to the design of a launch vehicle.

KEYWORDS:
Aerospace meteorology; Launch/space vehicle development; Mission operations; Atmospheric environment; Atmospheric variability; Meteorological rockets; Sequential detail wind profiles

Balloon release time	Purpose
L-6:15	Balloon consists of design, High-Q verification, and roll maneuver verification. This is a final system check-out balloon and the first of trending data for the day. It also serves as a second backup to the designed I-loads and they should be used.
L-4:50	Balloon consists of the prime design, High-Q verification, and roll maneuver verification. This is the planned time to design the trajectory I-loads.
L-3:35	Balloon consists of High-Q verification and roll maneuver verification. This is the backup design balloon to the L-4:50 and the backup to the prime High-Q verification balloon at L-2:20. The L-3:35 balloon is assessed with 3.5 h of wind persistence.
L-2:20	Balloon consists of the prime High-Q verification. This balloon is assessed with 2 h wind persistence.
L-1:25	Balloon is a contingency High-Q verification one. Should certain conditions exist, this balloon will be the prime High-Q verification.
L-1:08	Balloon is the prime roll maneuver verification.
L-0:50	Balloon is the backup roll maneuver verification.
L+0:15	Balloon is used for post-flight trajectory analysis.
