An unmanned Airbus drone aircraft, a 75 kilogram Zephyr, flew for almost 26 days. It will offer local satellite-like services and runs on solar power. It flies in the stratosphere at an average altitude of 70,000 feet and has a wingspan of 25 meters.
Airbus has two variants of the Zephyr, designed to accommodate a variety of payloads.
The production model Zephyr S has a wingspan of 25m and weighs less than 75kg. It is able to carry see, sense and connect payloads.
Currently in development, the larger Zephyr T has a wingspan of 33m and weighs 140kg. It’s a larger size enables it to accommodate payloads with larger masses

Cool. A poor man’s satellite. Will these planes even show up on radar? Imagine an “aircraft” designed to be so nebulous that you couldn’t hit it with a missile because it would pass right through it but still be able to lift a communications/observation package. You would have to use an area effect weapon (MOAB) to kill one.

Why do we get an artist’s impression of an existing aircraft, rather than an actual photo?
What is the PV area? 20m^2? Maybe 5kw? Does it need that much propulsion to loiter?How much does a 60kwh battery weigh? More than 75kg? Without any details provided it sounds like a pretty remarkable drone. Getting it to altitude must be a biotch.

Assume it´s another use, operating drones from containers in Nevada desert is expensive and is U.S technology…and being so, unreliable. Europe is doing it with a wider scope, vigilance,communications,internet, multi role and inexpensive.

I also don’t understand why isn’t there a huge for a technology like this.Would be much cheaper than having someone launch a satellite in a huge rocket. Drones like this would fly into position themselves.
Interesting. Though I can’t help but think that a helicopter would be better. If memory serves a high aspect-ratio wing is most efficient for hovering (which means a helicopter’s rotor). Plus the solar panels could (should) be separate from the airfoil. Which could be hung from a cable (with the batteries for extra stability) and would have solar tracking, a further efficiency gain.

An missile would go of then hitting and this is an very slow moving target, all relevant missiles also has proximity fuses. But yes it would be easy to make stealthy and its small. You also need an pretty large SAM to hit something 20 km up, think it require an SAM system not just one truck. And as this looks cheap as in 125 kg you can easy use many.
Helicopters uses a lot more power to stay in the air than planes. Their only benefit is that they don’t need an runway and can hover. None is needed here. An solar powered plane can also glide part of the night, reducing the battery size.

Not necessarily. It depends on the proportions of the wings/rotors. Common helicopters are burdened by practicality and the need to provide both lift and movement. These wouldn’t effect stratospheric helicopters. They wouldn’t need to move and really long rotors won’t chop up trees or people. Imagine the rotors being of similar length and aspect ratio as the wings on these drone planes. “An solar powered plane can also glide part of the night, reducing the battery size.” I don’t know what you mean. They can’t just glide, they’d just loose altitude. Probably faster than a helicopter designed for that height. If you mean soaring, I’m quite sure that doesn’t come into play at those heights. (And would effect both the same anyway.)
