Features of a Hot Air Balloon
The envelope is constructed of nylon or polyester fabrics and is reinforced with strong webbing tapes known as load tapes. Horizontal load tapes go around the circumference of the envelope and the vertical load tapes from the bottom to the top of the envelope. See the diagram below.
Not shown on the diagram is the crown. The vertical load tapes come together at the centre of the circular top opening (above the parachute) and attach to the crown ring. The crown ring is a metal ring to which the crown rope is also attached.
