Shaping the tire with "saucers." Spinning discs which are delicately controlled by movable arms smooth out each layer of fabric as it is added to the growing carcass, and curves around the sidewall and bead with considerable pressure. In the center foreground, one of these saucers may be seen as this tire builder maneuvers it around the sharp corner of the tire drum. In the right foreground two others pull across from the center to the edges to smooth out each layer. Firestone (General Tires), Akron, Ohio

Barrage balloon manufacture. Fitting a manhold vent in the sidewall of a barrage balloon. These workers are putting in the final pieces of equipment on a completed barrage balloon, just prior to its deflation, packing and shipping to an army air base. In the foreground is a balloon ready for test inflation with air which will also be inspected during inflation. General Tire and Rubber Company, Akron, Ohio

Putting tire into curing mold. From the vacuum expander, the potential new truck tire is taken to this "watch-case" curing mold in which it is baked under high heat and pressure for a long time. The exact time and temperature varies with the type and size of tire. The airbag inside the carcass is filled with live steam during this process so that heat is added from both inside and out. The mold contains the tread pattern, or design, as well as all markings which will appear on sidewall. Under this heat and pressure the rubber turns semi-liquid, and flows into every crevice, completely bonding the rubber processed fabric carcass to the cushion, the cushion to the tread. After this operation it is now one unit--a complete tire. Firestone (General) Tires, Akron, Ohio

Covering the beads. Beads are covered with sturdy fabric which builds back down into the sidewall of the finished tire for added strength. Passenger tires are normally supplied with only one wire bead, but truck tires usually have two or more, depending upon the size, weight and number of plies. Firestone (General Tires), Akron, Ohio

Shaping the sidewall. Moistening the bead area with a special rubber solvent and cement, the tire builder makes ready to force the overhanging edges down and around to the bead where it will first be anchored, then trimmed. The wheel spins and stops by foot control, leaving both hands free for work upon the tire itself. Firestone (General Tires), Akron, Ohio

Supersonic Aircraft Model The window in the sidewall of the 8- by 6-foot supersonic wind tunnel at NASA's Glenn Research Center shows a 1.79 percent scale model of a future concept supersonic aircraft built by The Boeing Company. In recent tests, researchers evaluated the performance of air inlets mounted on top of the model to see how changing the amount of airflow at supersonic speeds through the inlet affected performance. The inlet on the pilot's right side (top inlet in this side view) is larger because it contains a remote-controlled device through which the flow of air could be changed. The work is part of ongoing research in NASA's Aeronautics Research Mission Directorate to address the challenges of making future supersonic flight over land possible. Researchers are testing overall vehicle design and performance options to reduce emissions and noise, and identifying whether the volume of sonic booms can be reduced to a level that leads to a reversal of the current ruling that prohibits commercial supersonic flight over land.
