i 4 TWELVE MEDFORD (OREGON) MAIL TRIBUNE Sunday. April 23. 1950 Radical New Plane Designed by Local Man After Study Emmett Tucker Jr., son of the famed Sno-Cat's inventor, and a member of the firm of Tucker and Sons, Saturday described a revolutionary new type of air craft which he has designed after several years of study and work. The Diane is a unique com bination of helicopter and sta-tinoarv-wina aeronautical prin ciples, Tucker explained. The body of the plane itself, in the present stage of design, is small and more or less conventional. It is tie arrangement of airfoil and engines which are redieally different than those on any exist ing plane. Lifts Vertically The plane Is designed for ver tical taKe-otts. at, mis stage 01 flight the airfoil acts as rotor blades considerably larger than the blades of conventional hell copters. They are powered by two engines set in the rotors themselves, as compared to the usual location of the engine in the body of the plane. The en gines are faced in opposite direc tions, one on each blade, on op posite sides of the plane. When eiiirfpri thpv will rotate the ro tor at a speed sufficient to lift the plane vertically. Thus far, the operation is not radically different from present helicop ters. , . Ti u whpn the Diane has achieved a considerable altitude in its vertical flight that the new principle comes into opera inn At least one engine is . Acm Telephoto TEST FLIGHT T18 Navy's new 60-ton petrol bomber, the XP5Y-1, takes off from San Diego Bay on its first test flight. The flying boat, which is hoped will be one ot the answers to the submarine in event of war, has four turbo prop engines developing a total of 22,000 norsepower. The XP5Y-1 is expected to hav a top speed of "more than 350 miles per hour' considered extremely fast for flying boats. Strange Sounds Bl amed on Meteors pnuinned with a reversible-pitch propellor. And the rotor blades Tor airfoil) are equipped with a innV vuhirh will hold them rigid ly at right angles to the plane s body. In addition, pitch of the rotor blades is controllable. Automatic Relays A a control lever is thrown in the cockpit, an automatic sys tem of relays takes over and rapidlv performs three tasks: (1) The rotor blades are halted in their rotation and locked at right angles to the plane: W me rotors are given the same pitch, thus changing them, in effect, from rotors to a stationary wing, and (3) the pitch of the propellor on the backward-facing engine is Up to this moment the plane Is. in theory, hovering In the air with no flying speed. As the rotor ceases whirling the plane noses over into a speed-gaining dive. As the propcllors, now both pushing forward, get a bite into the air during the dive, flying sneed is achieved, the plane lev els out and continues in con ventional flight. Reversei on Landing Landing is a reversal of this nrnr-eriurc. Tucker points out that If the principles he has worked out in theory prove out in practice, a whole series of problems in transportation would automatic ally be solved, several Mccuora people are interested in the de sign and us possiuiiiues, ne saia, and it is hoped to raise suffl cint funds to construct a fly ing model of the craft for experi mental purposes. An artist's drawing of Tuck er's conception of the plane ap pears on page 31 of the May is sue of Flying magazine, now on the news stands. THERE IS SPIRIT South Portland, Me. flJ.R) Mrs. John Dorsey sang at her sister's wedding more than 3,000 miles away. She made a record of the traditional wedding march in South Portland and sent it to Frankfort, Germany, where her army nurse sister became the bride of an air force pilot. ENJOY THE MAGIC OF FOR HOME, FARM and INDUSTRY JET PUMPS FOR LIFTS FROM i IP ? MM K4 iir VjJ lUllltlN PUMPS AND WATER SYSTEMS ro Diir By J. Hugh Pruelt Aitronomer, Extension Division, Oregon Higher Educ.Uon System After the aueer. unexplained noise of about noon March 5 had jarred the houses over a large part of the cloud-covered Lane County, Oregon, it was suggest ed that the commotion might have been of meteoric origin. It was soon evident that many as sumed that if this was the ex planation, the sound and jarring was due to a terrific thud of the meteorite as it struck the earth. That a large meteorite strik ing the ground would produce a jolt that could be distinctly felt In the immediate vicinity is un doubtedly true. But since such objects are so slowed down by the atmosphere that they los'a their t e r r if i c interplanetary speed and usually complete the last of the descent as freely-falling bodies, the impact would hardly be detectable very far. Source In Explosion Others believe that meteoric sounds have their source in the final explosion or breaking up of the meteorite in the air near the end of the visible flight, That there is often such a sound is known, but it too is of minor importance u s u a 1 1 y only a snapping noise and is heard only by those not very distant from it. The huge Yakima me teor of April 20, 1933, was re ported by several to have vis ually exploded rapidly three times just as it went out. An observer almost under this dis appearance point said that after about a minute he heard three distinct crackling sounds in rapid succession. Our calculations in dicated that the disappearance occurred 10 to 12 miles above the earth. With about 11 miles per minute as the known speed of sound in frigid air, this check' GREYHOUND Smie-M TOURS What fun! What economy!

Heard For 100 Miles The sound of a meteorite's tearing through the air at 20 or 40 miles per second is occasion ally heard faintly for 100 miles from the line of flight and with terrifying violence 20 to 30 miles away. It is often a guttcral bang followed by a rattling rum ble, which fades out in a few seconds. This most prominent sound comes from portions of the path usually a long distance from the end point. The air ahead of a speeding fireball Is intensely compressed; and immediately be hind it a high vacuum is momen tarily created. Mighty air waves ("Shock waves") hurled from these regions travel earthward with the speed of sound, approxi mately 11 miles per second in the subzero upper air. The fire ball itself far outspeeds these sound waves. Familiar To Veterans War veterans are quite famil iar with similar "shock waves" from artillery shells passing overhead with speeds greater than that of sound. Some de scribe the noise as being like a freight train roaring through a tunnel. This writer has three times from indoors distinctly heard aerial commotions that were completely proven to be mete oric. They have a characteristic quality shared by no other sound. Setback Study fo Resume Monday Further attention to a build ing setback matter is scheduled at a meeting of the city council Monday at 7:30 p.m. at the city nan. rne issue concerns the pro jected construction of a seven story apartment building at the corner oi loth street and Oak- dale avenue by Coates Construc tion company. Medford's plan ning commission has recom mended a seven-foot setback from the property lino for the structure. The commission proposal is opposed in a petition signed by property owners of the area. They feel that the required aver age setback, about. 20 feet, should be observed. The com-Pi-iy originally asked that the building be erected out to the property line. SNOW BALKS ESCAPE Minneapolis U.R) Two boys were tripped up by a snowbank as they tried to escape from a detention school. Police said the car the youths took to make a get-away stuck in the snowbank, enabling a police squad to catch mem. Welfare Recipients Soon To Receive Cash Portland, Ore., Apr. 22 (U.PJ The state welfare commission said today that general assist ance recipients soon will be given cash instead of requisition blames to buy groceries. The decision to switch to cash came after a conference among Commission Chairman Jack Luihn, Administrator Loa How ard and county welfare commis sion representatives. Oregon Independent Retail Grocers association had protest ed the reauisition blanks, charg ing that they were forced to ac cept the blanks whereas bate way stores had an arrangement with the commission to issue scrip. Assistance granted to depend ent children, the blind and the aged has been on a cash basis in Oregon for some years because federal money comes to the state commission. General assistance grants, however, have been han dled by the county welfare com missions on a requisition basis.
