Design Analysis of the FAIRCHILD C-82 PACKET

THE PACKET’S flight control system is a duplicate and dual installation consisting of cable sectors, pulleys, bellcranks, and push-pull rods. It is duplicate because there are two complete and independent systems —one on each side of the plane—and dual because, through a series of interconnections, either system may be operated from pilot’s or co-pilot’s station in event of failure of any part of either system.

DESIGNING TOMORROW'S PERSONAL PLANE

Now COMES the pertinent question: What is the matter with our first born—that is, the pusher? Not only was the pusher first to fly; it was also the type used by most of the early designers. Apparently a ‘natural’ for further development, it has been an object of care and attention ever since, its proponents including, at various times, some of the best brains in the business.

The ATOM NEW SOURCE OF ENERGY

A Tide in the Affairs of Men

On August 6, 1945, an atomic bomb exploded over the Japanese city, Hiroshima. Its concussion blasted the city, vaporized the fibre of Japan’s will to resist, and flashed across the world a light of such glaring intensity that even blind eyes could glimpse the forked road that is presented to humanity’s choice and destiny.

The Atomic Frame of Reference —Or Else

No LESS THAN IT awed the man-in-the-street, the disintegration of Hiroshima under the blinding blast of an atomic bomb likewise awed the man-in-the-aviation-industry. This, despite the fact that he has commonly taken in stride a full wealth of wonders in his own field.

MAINTENANCE

DE-ICER PUMPS DEMAND EXPERT CARE

THERE ARE TWO SIZES of this pump, the smaller one (Fig. 1) having a plain casing while the larger (Fig. 2) is provided with ribs for cooling. Each series is made with various drives, as shown in Table I. Otherwise there is no difference between the two so far as principle or servicing are concerned.

For Precision WITH Profit KEY THOSE COSTS

WITH AVIATION ENTERING the competitive phase of manufacture and distribution in the stringent economic period naturally following cessation of war, only those units of the industry which are able to reduce production costs to a minimum while maintaining standards of precision will survive.

War-Developed Radar Promises Swift Peacetime Progress

WITH THE WAR'S END it IS possible to reveal some of the long-suppressed technical details and to estimate the potential peace-time aeronautical uses of radar. Radar was an important factor in winning the war; it will be an equally important factor in the safety of civilian aviation, and in the speed with which air traffic can be handled at crowded airports which will result from increased civilian flying.

FOR BETTER DESIGN

Putting Taxi Stability Into Conventional Tail Gear

DURING TAXIING, the free-swivel wheel of the conventional tail gear renders the airplane directionally unstable, and pilot must constantly use the brakes for directional control. This instability becomes particularly troublesome on windy days and when considerable taxiing must be done.

...Toward Better COMBINATION CONTROLS

COMPETITION between mechanical, hydraulic, and electrical mode of actuation for various aircraft units has produced results that would probably not have been otherwise attained. Consequently, after maximum efficiency with minimum weight had been separately achieved with each mode of actuation it became obvious that combinations of the mechanical, hydraulic, and electrical systems, utilizing the best features of each, would afford performance not yet realized.
