‘Stealth Sheet’ Makes People And Vehicles Invisible To Drones By Suppressing Infrared Light

The stealth sheet was created by researchers that hope it will be used in battle. As weapons become more sophisticated with the advances in technology, so do the countermeasures to weapons. Researchers at the University of Wisconsin-Madison have invented the “stealth sheet,” which is a super thin sheet that can suppress infrared light. This can be used to mask people and vehicles that emit infrared light, which can normally be picked up by drones, heat-sensing night vision goggles, and infrared cameras, according to the Daily Mail. The stealth sheet is made out of a bendable silicon material, masks up to 94 percent of infrared light, and is only a millimeter wide. The co-author of the study, Hongrui Jiang, described the concept behind the invention. “You can intentionally deceive an infrared detector by presenting a false heat signature … It could conceal a tank by presenting what looks like a simply highway guardrail.” So far, the stealth sheet has been tested with a model of the hu…

Denali prototypes coming together in Wichita


Cessna Denali ile ilgili görsel sonucu




Three flying prototypes of Textron Aviation’s Cessna Denali are coming together in a Wichita factory ahead of a scheduled first flight in the third quarter, the manufacturer says.
All major pieces of the single-engined, nine-seat turboprop, including the nose, fuselage, wings and tail cone, are being fabricated.
Meanwhile, Textron Aviation engineers are continuing to run ground test articles through a battery of static and fatigue tests, the company says. The initial flight test articles of some components are also being built and tested.
As Textron Aviation’s answer to the Pilatus PC-12 and Daher TBM900, the $4.8 million Denali is scheduled to enter service in 2020 featuring a GE Aviation Catalyst turboprop engine.
The Denali is making progress as Textron Aviation nears the end of a decade-long wave of development activity. Two years after introducing the Cessna Citation Latitude, the super-midsize Citation Longitude is nearing certification with the US Federal Aviation Administration, the company says. Development of the large cabin Citation Hemisphere remains suspended while Textron Aviation awaits the results of Safran Aircraft Engines' ongoing review of the Silvercrest engine.
