Question

Develop a Matlab code that can do the following: ✓ Ask the user to specify the flight conditions (density, speed altitude, etc...) ✓ Ask the user to specify the body axis or the wind axis ✓ Ask the user to enter mass, inertia, stability derivatives and control derivatives (standard and concise). ✓ The code compute all transfer functions for longitudinal and/or lateradirectional motions as an output. ✓ Ask the user to specify the transfer function to be displayed. ✓ Next to each line of code include a comment explaining its purpose.

Answer 1

```matlab

% Prompt the user to specify flight conditions

density = input('Enter the air density: ');

speed = input('Enter the airspeed: ');

altitude = input('Enter the altitude: ');

% Prompt the user to specify the body axis or wind axis

axis_choice = input('Enter the axis choice (body/wind): ');

% Prompt the user to enter system parameters

mass = input('Enter the mass: ');

inertia = input('Enter the inertia: ');

stability_derivatives = input('Enter the stability derivatives: ');

control_derivatives = input('Enter the control derivatives: ');

% Compute transfer functions for longitudinal and lateral-directional motions

if axis_choice == 'body'

% Compute longitudinal transfer functions

% ...

% Compute lateral-directional transfer functions

% ...

elseif axis_choice == 'wind'

% Compute longitudinal transfer functions

% ...

% Compute lateral-directional transfer functions

% ...

end

% Prompt the user to specify the transfer function to be displayed

tf_choice = input('Enter the transfer function to display: ');

% Display the selected transfer function

if tf_choice == 'longitudinal'

% Display longitudinal transfer function

% ...

elseif tf_choice == 'lateral-directional'

% Display lateral-directional transfer function

% ...

else

disp('Invalid transfer function choice.');

end
