PCorFunction: Static Defect Correction

In NCAR/Ranadu: Functions for use with RAF aircraft data files

Static Defect Correction

Description

Corrections to dynamic pressure and ambient pressure

Usage

PCorFunction(p, q = 100, akrd = 2.5, AC = "GV", Sensors = "STD")

Arguments

p	Measured (uncorrected) ambient pressure (e.g., PSF), hPa (no default)
q	Measured (uncorrected) dynamic pressure (e.g., QCF), hPa (or any units that match those used for p) – default 100 hPa.
akrd	The angle of attack (degrees; 2.5 deg. default)
AC	Aircraft identifier, either "GV" of "C130" (default "GV")
Sensors	Normally "STD" (the default) but "R" for right pressure pair, C130

Details

This correction was determined from fits to the measurements from the Laser Air Motion Sensor, as described by Cooper et al., 2014. These do not apply to older projects; in particular, TREX and before (GV).

Value

The ratio of the pressure correction to the measured pressure. The correction to dynamic pressure is the negative of the returned value.

Examples

# using PSXC and QCXC because PSF and QCF are not in RAFdata
PCOR <- RAFdata$PSXC * PCorFunction (RAFdata$PSXC, RAFdata$QCXC, RAFdata$ATTACK)
## Not run: dPoverP <- PCorFunction (p, q, akrd, "GV")
