Hand labor, spare parts fuel group's plan for cheap rocket
By Amy Zamierowski
Kansan staff writer
Engineers who design rockets can use the latest technology and equipment, but KU students are trying to build a rocket from snake nails.
"Most of the parts will be things you normally wouldn't see on a rocket," said Joe Huwald, president of the Cheap Rocket Society. "In industry, they would buy stainless steel pressure tanks to hold the fuel. They are too expensive, so we are trying to use bottles we can get for free."
The society, which has about 15 members and was started in 1986, originally built model rockets. But a rocket with a liquid fuel engine.
Because the society wants to spend less than $2,000 for the rocket, it is trying to find free or inexpensive parts.
"Right now we are testing freon bottles to be used as fuel tanks," he
said. The society is modifying the bottles to withstand pressures of 650 pounds per square inch. The bottles are designed for only half that pressure.
To construct the engine, society members are cutting the parts they need out of a steel block, he said.
The rocket, which will burn kerosene, may be ready to launch by next fall. It will be about 1 foot in height and from 13 to 18 feet tall, he said.
The society plans to launch the rocket to an altitude of 10,000 feet, or about 2 miles. Huwaldt said.
we could have set an attitude that was higher, but then it would have cost too much for fuel," he said.
The society learned how to build rockets by researching theoretical designs in the engineering library in Learned Hall, Huwaldt said. Also, the general layout of rockets is discussed in aerospace classes.
When the rocket is ready, he said.
the society will need to obtain government permission to launch it at a rocket test range.
"We can't just take it out and launch it in our back yard because someone wouldn't want it landing in their back yard." Huwald said.
Huwald said that the society's first rocket would carry instruments to measure its speed and performance.
"If the rocket turns out to be relatively cheap and easy to build, we could build more," he said. If that happens, other groups or departments might use the rockets for experiments.
Jim Stillwell, society treasurer,
said that working on the rocket
provided an opportunity to apply
theory and practical knowledge.
"On paper, a plan for a rocket may look nice. But when it comes time to build it, you can see the problems with the plans." Stilwell said.
Computer-aided design program gives students professional skills
New requirements modernize classes
Instead of drawing on paper, fifth-year architectural engineering students this semester are required to design their projects using a computer.

Students use the Auto CAD program by Autodesk, which is one of several computer aided design programs that are widely used by engineers. Thomas Dean, acting chairperson of architectural engineering, said it was the most used program in the profession.
Students also must take a course to learn how to operate the program, Dean said.
"When the students graduate in May, one of the questions they will be asked is whether they can use CAD." Dean said. "CAD drawing is used at the entry level in almost every office."
Dean said that when the Accredited Board of Engineering Technology examined KU's architectural engineering program in 1988, they criticized the program for not having CAD computer stations.
ment by Domingo Polican, Lawrence graduate student, who won $5,000 of computer equipment in a national contest last year, Dean said. The rest were purchased through the department's supply and equipment fund.
"The computer is like a calculator now," Gill said. "If you don't know how to use it, you are handicapping yourself."
Since 1989, the department has acquired six Zenith computers that can run the program. One of the computers was given to the depart-
John Gill, Topeka senior, said a computer was a necessary tool in architectural engineering.
Gill said that he thought that architectural engineering students should learn how to use the computer program earlier than their senior year but that there was a lack of available computers.

Recycled paper soybean ink used in Daily Kansan
By Mike Brassfield
Kansan staff writer
The newspaper you are holding is made of 100 percent recycled paper. The words you are reading are printed with soybean ink, an ecological alternative to oil-based inks.
John Sayer, director of KU Printing Services, said that the University Daily Kansas had been printed with soybean ink for about two weeks. Printing Services first printed pages on Tuesday to days last month, printing random pages with the ink.
The soybean ink costs about 30 percent more than oil-based ink but Printing Services does not charge the higher cost.
"I'm concerned that with the problems in the petroleum industry, the supply of oil-based ink will become unstable," he said. "I believe that this source of ink will be cheaper in the long run. Plus, the soybean ink is better."
Sayler discovered about a month ago that the Kansan has been printed on 100 percent recycled paper since 2006.
"We knew that the paper had some recycled content, but it was a pleasant surprise to find out it was 100 %."
Printing Services buys the paper from Nationwide Papers in Topeka through a state purchasing contract
"I've been lobbying for three years to get recycled paper, and I think we can." Sayer was a teacher in school in Kansas to do this.
Bill Willey, marketing manager of Nationwide Papers, said recycled paper slowly was becoming easier to obtain because it was becoming more popular with businesses and consumers.
Willey said that the newsprint was bought from the Monistre Paper Company, which collects wastepaper from the city.
"It's an expansion market, and it's here to stay." he said. "In the past few years, the demand has really grown."
The Michigan-based company collects discarded newspapers and badly printed newspapers thrown away by the paper mills.
Ten to 60 percent of the content of Kansan newsprint comes from paper recycled by consumers, he said. The
Few paper companies offer recycled paper because wastepaper must first be de-inked, he said. A de-inking machine is used to re-ink the paper.
"We feel very fortunate that we found a source of recycled paper," he said.
