Old fighter jets can be recycled and used to create new ones

New Fighter Jet Components Can be Printed 3D

Rolls Royce

The fighter planes first flew in the 1970s were converted to fine powder and can be used for 3D printed components of the next generation aircraft of the British Royal Air Force (RAF). Experts say this is a more efficient way to make aircraft. It is less environmentally harmful and also solves the problem of procuring materials from countries under sanctions, such as Russia.

Robert Hyam Additive Manufacturing Solutions has developed technology to recycle important materials such as TI64. This is titanium with 6% aluminum and 4% vanadium. The UK Department of Defense has a large number of expensive, hard-to-sauce materials like TI64, but they are bound by outdated or broken aircraft and stored components.

The company was able to take turbine blades from Panavia Tornado, an aircraft used by the RAF from 1980 to 2019, and recycle them into nose cones of prototype engines that power the next generation of RAF fighters. Ta.

“The world is more expensive than before. Making products is more complicated and more expensive,” says Highham. “You can make them as effectively as possible.”

Highham says creating spherical particles from old parts is the key to printing high-quality new parts, as the jug-on particles may be stuck in a 3D printer. It’s not just grinding the metal, so the recycled components melt and then spray them onto a high-pressure jet of argon, where they are split into raindrop-shaped droplets. These droplets rotate the gas, turn into a spherical shape, drop out and solidify. “It’s a very similar process to how rain sparkles,” says Hyam.

The resulting powder can be supplied to a 3D printer. These machines essentially weld the powder into half the thickness of human hair, each layer down one by one, creating a new piece. “It’s a very simple microscope welding process. It’s not even more complicated,” says Higham.

In this first case, powder was used to 3D print nose cones for the Orpheus jet engine. Future Combat Air Systems (FCAS). The FCA includes a variety of aircraft with modular components, including the BAE Systems Tempest, a sixth generation fighter jet for the RAF.

Anduril Introduces Road Runner: A Fighter Weapon with Falcon 9-Like Landing Capabilities

Leading defense technology startup Anduril has developed a new product designed to address the proliferation of low-cost, high-power aviation threats.

The product, called Roadrunner, is a low-cost, designed, modular, twin-jet-powered, autonomous vertical takeoff and landing (VTOL) aircraft. Anduril is also developing a variant called the Road Runner Munition, or Road Runner M, which is a “high-explosive bomb interceptor.” This means it can also carry warheads and destroy air threats defensively.

The Roadrunner is unusual in both appearance and abilities. It can take off, track and destroy targets. When there is no need to intercept a target, the vehicle can autonomously maneuver back to base, refuel and reuse. As Chris Brose, Anduril’s chief strategy officer, said in a recent interview, “We’ve developed a fighter weapon that basically lands like a Falcon 9.”

The product was built in response to the rise of high-speed, autonomous air weapons that can be produced in large quantities and at very low cost, a new type of threat, Brose said. Unlike other current solutions and previous legacy missile systems, the Roadrunner-M is also reusable.

“In my opinion, this is the first retrievable weapon ever deployed in combat,” Brose said. “That’s really great. The ability to introduce […] If it is not actually used in an operation to kill another drone, it can be recovered and reused, completely changing the way operators fight with this feature. Currently, they have a limited number of interceptors and cannot take them back if they decide to launch an attack. ”

According to Anduril, there are several other major improvements compared to previous systems. These are: a reduction in launch and takeoff time, a threefold increase in the warhead payload, a tenfold increase in the effective firing range, and a threefold increase in maneuverability in terms of gravitational acceleration. Like Andruil’s other family of systems, Roadrunner-M can be controlled by Lattice, Andruil’s AI-powered command and control software, or integrated into existing architectures.

Another big benefit is for operators. When faced with a fast-moving threat, Roadrunner can launch instantly, image it, and receive a signal to engage or not. The products are reusable and recoverable, allowing operators to act without fear of losing valuable assets.

Brose said the company has been working in tandem with unnamed U.S. government partners since it began designing the Roadrunner about two years ago.

“[National defense] A lot of times, the stereotype is right that it’s just very dull, very slow, very unimaginative, very unexciting,” Brose said. “As a company, Anduril is the antithesis of that, and Roadrunner embodies the kind of excitement that we believe exists in national defense, and I think we’re very keen to bring that back.”
