What wood was bi plane made from?

Answer 1

Answer The old World War 1 biplanes were made of woodframe, supported by wires and covered with cloth. This process has continued to be used in airplane construction for many years and even some aircraft continue to have flight controls made of aluminum covered with fabric. The basic frame of the aiplane was made of wood. The frame was pinned or glued or attached with metal brackets. Then wires were attached internally to pull the wood joints together and add stiffness so the wings or fuselage would not flex as much. Over this, a fabic cover was applied using glue or "Dope". As the glue dried, the fabric shrunk and became very hard. This provided some stiffness and allowed the fabric to withstand the wind loads on the area not supported by the frame. After assembly of the fuselage and wings, more wire braces were attached to align and support the wings and tail.
