Pressure scoop: Hanging down from the bottom of the balloon, this fireproof material is used to direct cool air into the balloon. The cool air helps pressurize the inside of the balloon.

OBS

Semi-circular shape, used to scoop in air into the hot air balloon, hence increases the pressure inside. It gives a protection from gusts, just like a skirt.

OBS

scoop: A specialized-shape skirt which, on American balloons, narrows to an inch or two on one side and widens to extend all the way from the top of the poles to the base of the envelope proper, forming a tilted mouth. The idea of the scoop is to provide better control of the aerostat's orientation. Ideally, the front (or main part of the scoop) will always be kept in the direction of travel. It may also aid in keeping the envelope full.
