NO, IT ISN'T A CANNON—It's a jet engine. This pulse jet engine, given to the University several months ago, last week was tested at the Lawrence airport. The engine developed a thrust of 105 pounds, five more than it is rated to produce
What a Blast!—
Students Test Jet Engine
By TRACY BARNETT
The thermodynamic efficiency of a pulse jet aircraft engine has been tested at the Lawrence airport by aircraft engines laboratory students. It was the first time that the engine had been started since it was obtained from the U.S. Navy several months ago.
Ammon S. Andes, associate professor of aeronautical engineering, said that the test was unusually successful, since the engine developed higher thrust and efficiency than expected.
The engine tested was the same type of jet engine used by the Germans during World War II on V-1 rockets. The Navy, he said, used the jet to power a target plane.
Prof. Andes stated the thrust developed by the eight inch pulse jet was measured at 105 pounds. This was five pounds more than the engine is rated to produce.

Alumni Name Candidates
Pioneers and Trail Blazers slates of candidates for the 1953 elections of the University Alumni association have been named by Ray Evans of Kansas City, Kan., president of the association.
Howard G. Engleman, attorney in Salina, is the Pioneers nominee for president. Opposing him on the Trail Blazers ticket is Otto O. Schnell-bacher, Topeka insurance man.
Dean Ostrum, young war veteran and now a lawyer at Russell, is the Fioneers nominee for vice president. His opponent is Paul Masoner, former football and track star, now an investment company in Garden City. The presidency and vice presidency are for one-year terms.
The Trail Blazers committee nominated Clarence Coleman of Wichita and Harry G. Wiles of St. John for 5-year terms as directors.
Their opponents are Roy A. Edwards Jr., of Kansas City, Kan., and Fred C. Littoo, Hutchinson. Mr. Edwards is secretary-treasurer of the Rudy-Patrick Seed company, Mr. Littoo an attorney.
EXPERT WATCH REPAIR

WOLFSON'S 743 Mass.
The flutter valves are about two inches thick and eight inches square. The front side of this unit resembles a furnace grate, having several holes through which air can pass. The back side of the unit has several spring flaps which close the holes.
When the engine is in operation, air passes through the holes at the front of the unit until an explosion occurs in the tube. The explosion forces the steel springs together closing the holes and cutting off the flow of air. This process occurs 90 times a second and gases being forced out the back of the engine give it a forward thrust.
The students started the engine with compressed air, batteries, and spark plugs. Compressed air was forced through the front of the jet engine from a portable compressor.
When the air flow was great enough to cause the 80 octane gasoline to vaporize, a student turned on an electric current which caused the initial explosion in the engine. At that instant, the jet emitted a terrific roar and ran like a watch for about three minutes.
Prof. Andes said that the thrust created by the engine would be sufficient to power a light plane like a Cessna 140 in flight at about 100 miles per hour. He stated that the engine would use two pounds of fuel per second.
The pulse jet engine is one of three jet engines owned by the University, he said. The Navy also gave the University two XJ31-5 turbojet engines which were built by General Electric company. The turbo jets, he said, have 16 times more thrust than the pulse jet.
Prof. Andes hopes that it may be possible to demonstrate the pulse jet engine at the Engineering Exposition to be held at the University April 17-18.

Teachers to Meet In Special Classes
The School of Education will sponsor two workshops and a seminar this summer.
The seminar in core curriculum will be held June 15 to June 26. Members of the staff will include Dr. Cloy S. Hobson, professor of education, and Dr. Karl D. Edwards, assistant professor of education.
Applicants must have their transcripts from previous colleges sent to the director of admissions not later than June 6.
From June 29 to July 10 a workshop will be conducted in the Memorial Union on the problems of administration of a school plant. Dr. Cleve Q. Westby, State Department of Education in Trenton, N.J., will be the visiting consultant.
"I do wish they'd build a bridge over Reginald's North Lawrence short cut."
"Problems in the Administration of the Pupil Personnel Program" will be the title of the workshop being held July 13 until July 24. Visiting consultants will be Dr. August Jameson, associated consultant in Education at Chicago, and Robert MacNevin, department of public services at the public schools in Kansas City, Mo.
Fees will be $15 for each two-week session and a matriculation fee of $10 for Kansas residents, $20 for non-residents. Housing will be available in University facilities for $2 a night.
Outstanding Senior To Be Given Award
The establishment of the Agnes Wright Strickland memorial life membership in the University Alumni association has been announced by Ray Evans, president.
The children of Mrs. Strickland, who was a resident of Wichita until her death Christmas night at the age of 85, have established a fund with the KU Endowment association from which the income will purchase a paid-up life membership for an outstanding senior each year.

Debaters Enter National Tourney
One participating and one alternate debate team have been chosen on the basis of season records to attend the West Point Elimination Debate tournament at Ames, Iowa today and Tuesday.
Orval Swander, business senior, and Don Hopkins, special student in law, will make up the regular team. Letty Lemon, college sophomore, and Margaret Smith, college freshman, will debate as alternates.
Arguing the national question, Resolved, that the congress of the United States enact a national compulsory Fair Employment Practices law, teams will participate in four elimination rounds and four final rounds.
Sixteen teams from Wisconsin, Minnesota, Iowa, Nebraska, Kansas, Colorado, and Oklahoma will attend the meet, the four high teams after final debates, go to West Point to compete for the national championship.
"This tournament is the debater's counterpart of the NCAA regional playoffs, and a mighty important one to win." Kim Giffin, debate coach, said.
2 Aero Engineers To Appear Here
Two aeronautical engineers from aircraft companies in Wichita will speak at the University this month and in April at meetings of the student chapter of the Institute of Aeronautical Sciences.
The first speaker will be M. J. Gordon, chief aerodynamist of the Beech Aircraft corporation, who will speak at 7:30 p.m. Monday March 30, in Lindley auditorium. His address will be on the aerodynamistic's part in aircraft design. He will also show a film on the development of the Beech safety shoulder harness.
The second speaker will be Charles Siebel, chief engineer of the helicopter division of Cessna Aircraft, who will speak at 7:30 p.m. in Lindley auditorium for April 20.
