Requisitos

2. Build a balsa wood glider from a kit and observe its flying characteristics as related to variable positions of the wings.

SIG Manufacturing is a major supplier.

3. Make and successfully fly two different styles of paper airplanes using sheets of paper between eight (20.3 cm) and fourteen (35.6 cm) inches in width and length.

Paper Plane with airfoil wings is a fun paper airplane to build. It requires more than simply folding a piece of paper up, and can be used to teach the concept of Bernoulli's Principle.

Boy Scout Paper Plane plans include many creative and fun paper airplane plans.

4. Define, locate, and explain the usage of the following basic items:

• Fuselage
• Wing
• Aileron
• Rudder
• Horizontal stabilizer
• Strut
• Cockpit
• Engine
• Landing Gear
• Propeller

Fuselage

The elongated body or frame of an airplane, any kind of frame or body. The central body of an airplane that is designed to accommodate the crew and passengers (or cargo).

Wing

Any surface used primarily for supporting an airplane inflight by forward motion.

Aileron

Ailerons are movable control surfaces that are present on the trailing edge of both the right and left wings of a plane. Each surface moves in opposite directions enabling a plane to roll right or left. For a plane to roll to the left, the left wing aileron moves upwards while the aileron on the right wing moves downwards.

Rudder

This is the term used to describe the part of the tail that moves back and forth. This movement causes the tail of a plane to move which then turns the plane.

Horizontal stabilizer

The horizontal "mini wing" at the tail section of the airplane. The elevator is attached to the horizontal stabilizer with hinges.

Strut

A diagonal brace going from the fuselage to the bottom of the wing consisting of a bar or rod used to support the wing on the airplane.

Cockpit

Compartment where the pilot sits while flying the aircraft.

Engine

The source of power to turn the propeller or turbines and generate thrust. Can be an internal combustion engine, jet engine, or in the case of an airplane model a rubber band engine.

Landing gear

An undercarriage that supports the weight of the plane when it is on the ground.

Propeller

The mechanical device attached to the engine that rotates to push against air and create thrust.

Dihedral

Dihedral is where the right and left wing tips are higher than the fuselage. More dihedral generally means that a plane will be more stable in the air, but will be more difficult to turn. Most planes require a bit of dihedral to fly well.

Elevator

Elevator is the term used to describe a plane's horizontal control surface on the tail. This surface enables a plane to pitch upwards or downwards. When an elevator surface moves upwards, the tail moves downwards (the nose of the plane then points up) and vice-versa. Without an elevator, it is hard to control the altitude of a plane as you can't control the rise and fall of the nose of the plane.

Thrust

The mechanical force generated by the engine to move the airplane through the air.

Vertical stabilizer

The vertical fin which is part of the tail assembly of the airplane. The rudder is attached to the vertical stabilizer with a hinge.

V-Tail

V-Tail aircraft are planes that have only 2 stabilization surfaces (in the shape of a V) instead of a conventional horizontal and vertical stabilizers. In a V-Tail aircraft, the 2 control surfaces of the V-Tail work together to give elevator and rudder responses.
