Model Airplanes

Addressing a large and fervent congregation of the people on Tehran University campus on Friday, Ayatollah Movahedi Kermani said, “The manufacture of Iranian drone based on the US RQ-170 spying drone, which was captured by the Islamic Revolution Guards Corps (IRGC) Aerospace Force was a major blow to the US.”

The Iranian version of the RQ-170 drone has been manufactured through the reverse engineering of the US drone which was tracked and hunted down in Iran late in 2011 and has been equipped by the IRGC with bombing capability.

On Wednesday, Commander of the Islamic Revolution Guards Corps (IRGC) Aerospace Force Brigadier General Amir Ali Hajizadeh announced that Four Iran-made RQ-170 drones – manufactured through the reverse engineering of a similar American pilotless plane that was downed by Iran in 2011, will start operational flights by the end of the current Iranian year (ends March 20, 2015).

“We have plans to bring into operation, at least, four indigenized RQ-170 drones for missions by the end of this (Iranian) year (March 20),” Brigadier General Hajizadeh said after the state-run TV displayed the footages of the first flight of an Iran-made RQ-170 drone.

“We will not extradite the US RQ-170 drone since it is a (war) trophy, but if the US sanctions against Iran are lifted, maybe we will give the US an Iranian model of the drone,” Hajizadeh added.

He said that the Iranian version of the RQ-170 has been built through a combination of the US designs and ideas

When a local product development company wanted to develop a hands-free buoyancy control device for scuba divers, it turned to Wichita’s RapidPSI for help.

Using three-dimensional printing, RapidPSI turned multiple revisions of the product into a smaller, more reliable unit that’s now ready to market.

The growing company takes 3-D computer-aided design drawings, or CAD, and using a 3-D printer, builds up objects in three dimensions, layer by layer.

Plastic materials are fed into the machine and heated “like a hot glue gun,” said RapidPSI vice president Jeremy Weinman. Essentially, the filaments are welded together.

“We’re a modern day machine shop,” Weinman said. It’s the largest 3-D printing company in Kansas, he said.

The 3-D printing process eliminates waste and the need for injection molding, set-up costs and the cutting, sanding and drilling found in traditional manufacturing methods.

Designs can be customized and changed easily.

“You just update the CAD model and send it over, and we can print out a new (part) the same day or the next day,” Weinman said.

The company, located at 1367 S. Anna, has changed a lot over the past five years.

Five years ago, about 80 percent of its business was urethane casting and the making of products from polyurethane materials, Weinman said.

The company used 3-D printing to make the tooling, then produced the parts in its casting division.

Now, that’s only about 20 percent of its business. Eighty percent is building prototypes and production parts through the 3-D printing process.

The majority of RapidPSI’s work is for the aviation
