0899

Item 0899

DESIGN: UniCopter ~ Dimension, Area & Drag - Dimension & Area - Side, X-Z plane

Mockup Base:

The mockup base is 49.0000" below the origin of coordinates.

Drawing:

Grid is 3" x 3"

Body Axis System is used.

Origin of Coordinates

Indicates a calculated field.

Rotors:

	Arm Length:
	Longitudinal (a.c. to origin)	x_P & x_S	0.0	ft.

Fuselage:

The canopy, with doors, will have a drag coefficient of approximately 0.8 and an area of approximately 12 sq-ft.

The canopy, without doors, will have a drag coefficient of approximately 1.2 and an area of approximately 7 sq-ft.

The rear canopy will have a drag of approximately 0.7 and an area of 5 sq-ft.

The boom will have a drag of approximately 0.6 and an area of 4 sq-ft.

Landing Gear has not yet been included with fuselage, above.

Physical Parameters:	Symbol:	Value:

Arm Length:
Longitudinal (a.c. to origin)	x_F	0.0	ft.
Vertical (a.c. to origin)	z_F	2.0	ft.

Note The plan view of the fuselage could have a different aerodynamic center to origin length on the longitudinal axis then the side view. The symbol above x_F is the same for both. This could be applicable to the longitudinal view as well.

Vertical Stabilizer:

The vertical stabilizer will have a drag of approximately 2.0 and an area of 4 sq-ft. The winglets will have a drag of approximately 1.0 and a combined area of 1.5 sq-ft.
