Show Build Steel War Balloons Metal Aircraft to Carry Twenty Passengers Pas-sengers Sleeping Bunks and Two Aeroplanes Vienna At the Daimler Motor works here a dirigible balloon of soft steel Is being built Instendof using I rubber nnd silk like Capt Thomas I S Baldwin the American airship builder or aluminum like Count von I Zeppelin Horr von Walach the Austrian Aus-trian Inventor makes his entire gas balloon of steel j I Though the craft Is well advanced In construction details are carefully guarded Its size cannot be learned but It Is known that the steel walls of the balloon will be a little over a half Inch thick and consist of many 39x39 plates All the plates are welded in annular form by an electrical elec-trical process The balloon Is of the familiar cigar fehnpo painted with a specially invented In-vented mixture to make It airtight and Is covered with a silk paper instead In-stead of silk cloth to reduce friction fric-tion The estlmaed weight of tho balloon Is over 28000 kilos and of the gasoline engine fuel about 2500 kilos This fuel will enable the ship to sail 24 hours Following tho Zeppelin principle tho gas reservoir is to have three com pnrtments to enable tho craft to keep afloat In case any one compartment is injured This feature Is In line with tho decision reached by tho French aeronautic engineer in building build-Ing tho new array airships The car is to accommodate 20 pas sengors ns woll ns extra ballast In the form of two aeroplanes of the Far man type All arrangements will be I made to provide cooked food for pas sengers and crew which will be pro pared on board There will nlso be miniature salons and sleeping bunks It is proposed to carry aeroplanes to use them In case of war like torpedo tor-pedo craft Tho great airship Itself Is regarded by the Inventor AS a large ironclad It will naturally be able to resist attack that would destroy rubber rub-ber or aluminum craft and will bo so constructed that it can ram aerial opponents Being made of steel it can hold gas far better than any other vessel It is not so affected by changes in tho atmosphere which cause contraction anti expansion and will lose only u small percentage of Its buoyancy in a year |
