OUR AIRCRAFT ENGINES, like everything else connected with military aviation, have come in for a lot of discussion in recent months. What are the facts about the power plants that are the hearts of our fighting planes? What do they do, and how do they compare with those of our enemies and our allies?

I AM AN inventor and have just developed a new type of dinner plate which I wish the world at large to know of—specially editors, who are busy men. The plate is marked with a number of arrows all pointing toward the center of the plate so that a man sitting down to his dinner will have no trouble locating his dinnermeat ration.

WHEN America’s new Army swung into action against the Nazi foe in North Africa, and on every important fighting ground since, our battling divisions went into combat behind a fast-moving screen of highly trained mechanized cavalry—scouting the enemy, probing delicately for his strengths and weaknesses, pouring back a flood of vital information that enabled our commanders to dispose their troops to the best advantage.

New Yarn Stretches Rubber Supply

AN ELASTIC yarn that is, however, not a synthetic rubber has been created from a vinyl-resin compound and is being substituted for rubber in military webbing, tapes, goggle straps, and undergarments for the “WAACS.” It hasn’t quite the stretch of real rubber, and its tensile strength is not up to heavy duty, but its resistance to weather, to body and mineral acids, and to many poison gases makes it superior to rubber for many light uses in war.

JACK O'BRINE
RADIO has produced a new marvel—a sprightly offspring that’s doing big things for our war effort while still in its swaddling clothes. RCA engineers, who divulged its arrival, call it “radiothermics.” Resembling its brothers only in the wonders it conjures, radiothermics gives the “hot foot” to slow production methods.

THE first job that aircraft had in any navy was that of looking around for the fleet. As soon as Glenn Curtiss landed his tiny seaplane alongside the U.S.S. Pennsylvania in February 1911, even the most shellbacked of naval sea dogs had to admit that the airplane was capable of outscouting any other observation device.

HELICOPTERS are being made for the Army by the Vought-Sikorsky company as the result of successful tests on an experimental model. Although this type of craft is limited in speed and lifting power, it has the great advantages of being able to rise and descend vertically, fly either forward or backward, hover motionless over a given spot, and operate from land, water, snow, or thin ice.

THE prophets of air power, from Douhet to De Seversky, have had their innings in this war. Armies have been swept away, great warships have been sunk, and cities have been battered into ruins by relatively unopposed air armadas. The argument seemed to be clinched.

PORTABLE steel bridges, capable of supporting 10-ton loads, are used by U. S. troops for quick crossings of ravines and narrow streams. Each bridge consists of two lattice steel girders on which wooden flooring is laid. To place a girder, a launching nose fitted with wheels is attached to the end and 20 men shove it on rollers across the gap.

Wellington bombers equipped with a huge steel hoop encasing a live magnetic coil were used for the dangerous work, which required the planes to fly only 60 feet above the water.

I HAVE just spent two days trying to absorb a quick glimpse of a fantastic future. My feet hurt from walking so far; my eyes ache from straining to see so many complex things; I feel somewhere between a state of brain fag and bewilderment, from trying simply to appreciate the immensity of an act of industrial imagination and faith so vast that it is beyond the possibility of quick human comprehension.

JUST as straw is spread on newly graded road banks to prevent erosion by rain, so sod may be packed around the base of a large tree to keep rain rushing down the trunk from washing out a newly seeded lawn. In the photo, a protected section successfully weathered a heavy rain, while the unprotected area was ruined.

A GREAT many double-hung window frames are built without removable facings on the pockets. If a cord breaks, or if it comes loose from the sash or weight, the repair cannot be made without first removing a casing. This should be done after the stop is removed by prying the outer edge with a chisel braced against a strip of metal or thin plywood to prevent damage to the plaster.

TESTS ON BATTERIES from a portable receiver should always be made with a voltmeter—it is the only testing instrument that will show accurately the effective voltage of a battery. It is risky business to use any other device, including a flashlight bulb or an ammeter, since many of them are likely to affect the life of a battery materially.
