...platinum and nickel wires (weight i½ Ib.) over which the exhaust gases pass. This bridge is electrically connected, through a tiny battery, to a sensitive ammeter on the pilot's (chauffeur's) instrument board. If the fuel mixture is too rich, the unburned gasoline vapor-hydrogen, carbon monoxide-will cause the platinum wires to glow hot (by its catalytic property), resist electricity. The battery current is thus shunted back through the nickel wires, to register on the graduated scale of the dial exactly what percentage of fuel is not being burned. Dr. Hutchison estimated...
Supporting Inspector McWade's story was a memorandum by the late Lt.-Col. V. C. Richmond, who was killed in the crash, filed last July after an unimpressive test flight of the R-IOI. Lt.-Col. Richmond found the hydrogen bags fouled against nuts and bolts at hundreds of points; that padding was ineffective; that the loss of lifting power was about one ton per square inch of hole in twelve hours?"an alarming condition. . . . Until this matter is taken in hand, we cannot recommend any extension of the flying permit...
...dope" (cellulose acetate or cellulose nitrate) used for coating aircraft fabrics. Question before the crash court of inquiry in London this week: Were the rats in the wreckage French rats or were they British stowaways in the R-101, had they gnawed a freshly doped balloonet of hydrogen until the gas leaked...
...sluggish pistons. Instantly the compressed-air tank and the engine burst, the explosion throwing the crew and their one passenger 40 ft. to the ground, wrecking the fore part of the gondola, scattering a shrapnel of splinters. Flames from the carburetor shot upward but burned out without igniting the hydrogen-filled...
Helium. The explosion of the 5,500,000 cu. ft. of hydrogen inflating the R-101 caused practically all the devastation. Rear Admiral William Adger Moffett of the U. S. Navy last week pointed out that if non-inflammable helium (gas next lightest to hydrogen) had been used the R-101 would not have exploded. British commentators had already noted this obvious fact, with the implication that the U. S., monopolist of the world's helium supply, had selfishly prevented any of the gas from being exported. President Hoover deemed this insinuation worthy of White House denial. The Department...
