America's Largest Aerial Battleship

Caption 1: The nose of the ZR- 2 (R-38) carries a conical mooring-eye that fits into a universal joint on the mooring-mast. The bow is reenforced with extra girders to withstand this strain and to prevent the nose from being blown in

Caption 2: The girders are of duralumin, almost aluminium-light and steel-tough. Miles of wire are used in the internal braces that stay the rigid framework. Only the main radial wires are shown here

Caption 3: The maximum speed is from fifty-five to sixty-five miles an hour. The placing of the cars differs radically from that of the R-34. There are seven instead of four, and the flying controls are separated from the engines. The dirigible is propelled by six 350-horsepower English engines, four direct drive and the after two geared. The ZR-2 is considerably faster, carries more gasoline, and has a greater cruising radius than the R-34

Caption 4: Rudders and elevators are of the balanced type. Air pressure on surface lessens strain on the controls. The fins are V-shaped and internally braced in order to reduce air resistance

Caption 5: Here is the interior of the control car. The ZR-2 is steered by large wheels. All of these complicated instruments must be watched constantly, and frequent calculations based on their readings termine how to trim ship and maneuver for a landing
