F-22 Raptor receives 3D-printed metallic part for the first time

F-22 Raptor receives 3D-printed metallic part for the first time

Business
Jan. 18 (UPI) -- A metallic 3D-printed part has been installed on an operational F-22 Raptor for the first time, which the Air Force hopes will lower costs and reduce maintenance time. The new titanium part for the cockpit, which was installed by the 574th Aircraft Maintenance Squadron at Hill Air Force Base in Utah on Wednesday, replaces conventional aluminum ones, the Air Force said in a news release. "One of the most difficult things to overcome in the F-22 community, because of the small fleet size, is the availability of additional parts to support the aircraft," Robert Lewin, 574th AMXS director, said in a statement. The Air Force noted 3D printing allows for replacement parts on short notice without minimum order quantities. The printed bracket, which won't corrode, is made from a...
World's smallest dinosaur tracks reveal new sparrow-sized raptor

World's smallest dinosaur tracks reveal new sparrow-sized raptor

Science
Nov. 16 (UPI) -- Scientist's have traced a trail of tiny dinosaur footprints to a diminutive raptor. Researchers found the tracks of the sparrow-sized dinosaur inside a dried lakebed in South Korea. "They are the world's smallest dinosaur tracks," Anthony Romilio, researcher at the University of Queensland, said in a news release. The 110-million-year-old tracks date to the Cretaceous period, a time when dinosaurs shared the planet with mammals and birds. Researchers described their discovery this week in the journal Scientific Reports. "The diminutive sizes of these new tracks are extraordinary; the tracks were made by tiny dinosaurs about the size of sparrows," Romilio said. "Raptors placed only two of their toes on the ground, while the third toe was retracted like a cat's claw."[embe...
Raptor plunging to extinction in England

Raptor plunging to extinction in England

Science
The hen harrier, an iconic bird of prey, is heading towards the brink of extinction in England, new figures suggest. There are just four breeding pairs left in England and numbers are declining elsewhere in the UK.Scotland is the traditional stronghold of these raptors, but numbers have fallen 9% since 2010.Numbers of hen harrier pairs in Wales fell by more than a third over the same period.The birds of prey live primarily on heather moorland. The males are easily identified by their black wing tips. The females look completely different, with puffy brown plumage that helps camouflage them and their nests. But this iconic species is under severe threat, according to the Royal Society for the Protection of Birds (RSPB). Illegal killings, along with destruction of their habitat, are behind t...
