BirdMorphParam: Morphological data from bird

In Josephine-Tetteh/FlightSim-updates: R-Package for estimating energy consumption during avian flight

Description

This function creates a list of user-defined morphological description parameters of an input bird. At least three parameters need to be specified: body mass, wing span and wing area. This definition of the bird is then used by the other functions in the package to estimate flight performance.

Usage

BirdMorphParam(BMass, WSpan, WArea, C_db = 0.2, C_dpro = 0.2,
  ADensity = 1.23, grav = 9.8, k = 1.2)

Arguments

BMass	Body mass of bird in kilograms (kg)
WSpan	Wingspan (maximum distance between wingtips) of bird in meters (m)
WArea	Wing area (area of fully stretched wings) of bird in square meters (m2)
C_db	Body drag coefficient
C_dpro	Profile drag coefficient
ADensity	Air density
grav	Acceleration due to gravity
k	induced drag factor

Details

This function defines the morphological parameters of an input bird and some other variables for power calculation. At least three bird parameters, body mass (BMass), wing span (WSpan) and wing area (WArea), need to be specified.

The default value for both body drag and profile drag coeficient: C_db and C_dpro is 0.2. A constant air density of 1.23 kg/m3 is used with acceleration due to gravity, grav of 9.8 m/s2. The induced drag factor, k, is also given as 1.2 as used in the Flight Program (Pennycuick, 2008). All default arguments can be varied as suitable. If no arguments are defined, the default values will be used.

Value

Morphological parameters of bird and other variables for power calculation.
