Standard Atmosphere. The concept of a standard atmosphere is required so that we can perform comparisons of performance among different aircraft. On any given day it is likely that the atmosphere will not be standard.
This standard provides guidelines for selected reference and standard atmospheric models for use in engineering design or scientific research. The guide describes the content of the models, uncertainties
Here is the story—please read on. atmosphere gives mean values of pressure, temperature, density, and other properties as functions of altitude; these values are obtained from experimental balloon and sounding-rocket measurements combined with a mathematical model of the atmosphere.
24 wrz 2014 · This standard is intended to assist aircraft and space vehicle designers and developers, geophysicists, meteorologists, and climatologists in understanding available models, comparing sources of data, and interpreting engineering and scientific results based on different atmospheric models.
The Standard Atmosphere 1. Temperature is a specified function of altitude. Temperature is either constant with altitude, as in the stratosphere, or varies at a constant rate with altitude. This rate is called the lapse rate. In the troposphere the lapse rate is –3.56616degR/1000ft. 2.
Standard Atmosphere Modeling. For purposes of pressure altimeter calibrations, aircraft and rocket performance and their design, and so forth, knowledge of the vertical distribution of such quantities as pressure, temperature, density, and speed of sound is required.
Standard Atmosphere Computations. This form calculates properties related to the 1976 standard atmosphere up to 230,000 ft. The Javscript used is based on the original code of Ilan Kroo (kroo@leland.stanford.edu) 31 Dec 95. Select unit system: English Metric. Inputs. Tabulated ISA data. Results.
