The AFRL ordered the “Silent Arrow Precision Guided Bundle”, a new glider variant that is a smaller version of the “Silent Arrow GD-2000” drone, which Silent Arrow built for the US Special Operations Command.
The smaller Precision Guided Bundle UAV will be able to be launched from aircraft side doors and cargo ramps. Aircraft capable of deploying the drones will include those as small as Cessna Caravan turboprops and as large as Boeing C-17 strategic airlifters, the company says.
The autonomous unmanned air vehicles (UAVs) will be built at the company’s Irvine site, then shipped north for operational evaluations in 2022 at Pendleton UAS Test Range in Oregon, Silent Arrow adds.
The Silent Arrow line of cargo gliders have spring-loaded wings that fold for storage and deploy for flight. The type is advertised as being cheaper than the US Army’s Joint Precision Airdrop System, a GPS-guided parachute system used for delivering cargo.
The un-powered Precision Guided Bundle has a 34.8nm (64.4km) glide range and is “deployable from high altitudes and airspeeds”, says Silent Arrow. It is about 1m (3.3ft) long and has 159kg (350lb) of cargo payload capacity. By comparison, the larger Silent Arrow GD-2000 can carry 740kg of cargo.
Silent Arrow says Precision Guided Bundles will also have swarming abilities, likely meaning the UAVs will be able to share sensor data and work together to find landing zones.
The details: The flight was a significant technical challenge, thanks to Mars’s bone-chilling temperatures (nights can drop down to -130 °F/-90 °C) and its incredibly thin atmosphere—just 1% the density of Earth’s. That meant Ingenuity had to be light, with rotor blades that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth’s, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.
Why it’s significant: Beyond being a significant milestone for Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future helicopter drones could help rovers or even astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn’s moon Titan in 2027.
What’s next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity’s capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning around May 4.
When you get a drone you might think that everything you need will come in the box, and on a basic level that is true. Most consumer drones come with everything you need to have a satisfying flying experience. However, the more you get into the hobby of flying drones, you begin to experiment with different things and start understanding some of the other gear you might need to get the most out of your drone.
Drone accessories are an often overlooked yet important aspect of the drone flight experience. Accessories like a carrying case, SD cards, extra batteries and propellers, and ND filters will help you get the most out of your drone both in performance and lifespan.
There are many accessories for your drone, but before you start loading up on gear, you should make sure that the accessories you choose fit your specific drone model. If not, you might purchase something that doesn’t work for your model, and then you’ll have to go through the hassle of returning it and getting a replacement.
This article will help you think through some of the most necessary and best drone accessories in 2021, as well as helping you make sure you get the right gear specific to your drone.
As I said, most drones do not absolutely require you to add any accessories. They are sufficient on their own out of the box. However, after flying drones for a while, I have often found myself thinking that I wish I had a certain accessory that would simply make things more convenient or efficient.
That is why I have compiled the following list of accessories that are extremely helpful for anyone who flies drones.
