PROPELLER RING RAISES PLANE’S SPEED
That the speed of an airplane may be increased from thirty-nine to 140 percent by putting a ring around the propeller is the discovery announced by two Compton, Calif., inventors. The circular cowling is said to straighten out the air blast
of the propeller and increase its effectiveness. Vanes within the ring, which the inventors are indicating in the picture above, may be adjusted during flight to increase the air drag and so serve as brakes in landing.

Statement for MECHANIX ILLUSTRATED
by General Curtis E. LeMay
“For ten years the Strategic Air Command has stood ready as a most powerful deterrent to any aggressor threatening world peace. With with long range bombers and nuclear firepower SAC could carry to an enemy’s heartland the greatest destructive power the world has ever known.
“SAC., often called the world’s best insurance policy for peace, is the long range offensive arm of the USAF.
FLIERS GUIDE TO AIRPORT
THE WORLD’S largest gasoline container, located in Chicago, Ill, serves a dual purpose. In addition to having a capacity of 20,000,000 cubic feet of gas, it is also the first comparable industrial structure in the country to be marked and lighted according to specifications approved by federal and local aviation authorities.
The container is 283 feet in diameter and 416 feet from the ground.
French Midget Jet
The little Minijet zips along at 250 mph and may become the big liaison plane of tomorrow.
THE tiny jet aircraft shown above is no mere novelty, though it is undoubtedly one of the smallest jets yet built. In recent aerobatic competitions in England it placed second against a number of British, Dutch, German and Spanish planes that were not designed to look cute. It’s called the Minijet and its makers hope it will prove a useful training and liaison plane.
Jets are Jacks Of Many Trades
WHEN already overworked jets aren’t pushing airplanes, speedboats or racing cars, they are assigned to less glamorous jobs in Britain.
On the River Thames, dredging experts are experimenting with an aircraft jet engine to blast away dock-blocking mudbanks. If successful, the method may prove less costly and more effective than ordinary dredging.
Also a British innovation is the earlier use of a similar jet engine as a railroad snowplow during winter blizzards.
Trip to Europe Made by Air, Rail and Water
Crossing the Atlantic ocean by air has been removed from the category of high adventure to a regular form of transpor- tation running on schedule. For the traveler who is in a hurry, one steamship line has established, as a part of its regular service, a trip by air, rail and water which permits the tourist to cover three continents, or about 16,500 miles, in from nineteen to twenty-one days, depending on the speed of the steamer he uses. The three weeks’ trip spanning three continents covers North America, South America and Europe. From Miami the traveler goes by plane to Rio de Janeiro or Pernambuco, then he boards the “Graf Zeppelin” which makes regular trips from Rio de Janeiro to Friedrichshafen, Germany. From Germany the tourist travels by rail to Cherbourg, France, where he boards a liner for the trip to New York.
HIGH ALTITUDE HELMET
HIGH altitude flying has been made possible by use of oxygen for both men and motors. Lt. J. A. Macready of the Army Air Service is shown below with the latest type helmet.
The entire face is covered, and the glasses are built in the helmet itself. The tube that enters just below the nose furnishes oxygen to the aviator in any amount that he desires. The tanks are controlled by a valve.
Some of the early helmets for this service were very complicated and resembled an ocean diver’s top piece. As a consequence of their bulkiness they have given way to this new head piece, which combines both utility of purpose and streamline design.

NEXT year, your back yard may be an airport. At least it will if it’s 50 x 50 ft. or larger—and provided your budget can stand the sort of strain another automobile in the medium price class might place on it.
The family’s “second car” in this case, however, won’t be just another woe-on-wheels to clutter up the highways. This one’s designed, literally, to “rise above” traffic problems. In fact, it isn’t a car at all, but a little one-stick, two-seater helicopter so simple in concept that you’ll find yourself a pilot in a matter of hours—not months—after you buy it.
20 Distinguished World Airlines – and the U.S. Air Force and U.S. Navy – have selected
THE CONSTELLATION & SUPER CONSTELLATION
On every continent of the world leading airlines fly the famous Constellation. Today more people fly over more oceans and continents on the Constellations of these great airlines than on any other modern airplane. It is also the leader on the most traveled route, the North Atlantic. This successful operation by international airlines established the Constellation’s record for dependable performance—leading to the development of the new Super Constellation, today’s finest transport airplane.
This was a followup to a 1932 article on his efforts.
Fast Tank – and – Plane Latest War Machine
Combination of a high-speed tank and a fast plane is the new war machine being developed by Walter J. Christie. In military service, the tank would be attached to the fuselage of the plane to be transported to any point desired. Upon landing, the tank would be detached, free to advance on enemy positions.
