The delivery drone space is becoming increasingly crowded, but we tend to see slightly different flavors same basic designs and operating modes. There are point-to-point multirotors, point-to-point hybrid systems (such as tailsitters), is fixed-wing drones requiring launch and landing infrastructure. One thing that all of these drone platforms have in common is the scale: the current generation of autonomous commercial delivery drones are optimized for payloads of a few kilograms, offering high value and time sensitive payloads in low infrastructure areas.
There are many use cases where small drones work well, but once you need more than a handful of kilograms at the same time, there are few commercial options. The military have experimented glider drones is parafoil systems which can handle hundreds of kilograms e unmanned helicopters capable of handling over a thousand kilograms simultaneously. But in most cases, air freight delivery for commercial or (even emergency) purposes means using a small cargo plane such as a Cessna Caravan (if there is nowhere to land) or a helicopter. And this can be a challenge both in terms of costs and platform and availability of pilots.
ThereCraft, a Los Angeles-based delivery drone startup that was (mostly) invisible earlier this year, worked on a new design for a drone that can go from a few kilograms to 1300 kg. It uses a design that originated in the 1960s, along with a uniquely acrobatic delivery system that promises precision delivery without landing, flying or parachuting.
