SkyProwler 2

The 2019 SkyProwler 2 is the second generation of our VTOL transformer UAV.
Fly up to 80mph/130kph fast, fly for up to one hour.

For vertical take-off and landing (VTOL) SkyProwler 2 transforms by folding out its arms. When transitioning to fixed wing flight it folds these arms in to reduce air drag. SkyProwler’s 4K camera is 3D stabilized. Use the drop door for deliveries.

Airplane configuration - aerodynamically clean for fast, efficient forward flight

VTOL configuration - a big rotor disc area for efficient VTOL and hover

How is the 2019 Skyprowler 2 better than the 2017 Skyprowler 1?

The basic design principles of SkyProwler 1 and 2 are the same. SkyProwler 1 is an excellent UAV. Yet SkyProwler 2 has been much improved in many of the details and as a result is a significantly better aircraft. Compared to SkyProwler 1, SkyProwler 2:

  • Is ~3 ounces / 100 grams lighter

  • Has 20% larger wings for more payload and slower stall speed

  • Has 50% larger battery capacity

  • Has a lower/flatter and slightly shorter body, causing less air resistance

  • Has 10mph/15kph higher top speed

  • Has a 20 minute longer endurance

  • Has 15 miles/22km longer fixed wing flight range

  • Can carry a 3 ounces/100 grams heavier payload

  • Has a 30% larger cargo compartment under the wings

  • Instead of a two piece tail, has a one piece tail

  • Instead of 4, has only 2 lids on the top of the aircraft

  • Has a wider landing gear stance for more secure landings

  • Has a digital 1080 HD instead of an analogue video down link

  • Has a much longer range of the control and telemetry radio link - up to 10 miles/16km

  • Has a much better ground station, integrated into the carry case

  • Has two tablet screens integrated into the carry case, one for video (if camera ordered) and one for telemetry

  • Has an extendable antenna mast integrated into the case, to increase control and video range

  • Keeps the tail on during transport in the case, only wings and camera have to be taken off

SkyProwler 2 is faster, more stable, able to lift more, and able to endure longer before the battery has to be changed. It’s also easier to use and more quickly deployed.


Technical Data and Details

Switchblade Mechanism

The patent pending switchblade mechanism forms the basis of the transformation of SkyCruiser and SkyProwler. Airplanes need to fly fast and to fly fast you need to be as aerodynamically clean as possible. That's why airplanes are long and narrow, somewhat drop-shaped and with as few 'things' sticking out as possible.

For vertical take-off and landing on the other hand, you need to be the opposite of aerodynamic. The more things you have sticking out producing lift (think of the extreme of a parachute for example) the easier it is to hover. This is the main reason why helicopters which a great at hover, are not very good at forward flight, being slow as well as needing a lot of fuel.

The switchblade mechanism transforms an aircraft from the aerodynamically clean airplane configuration to the VTOL configuration, which features a number of rotors that together have a large rotor disc area that is ideal for hovering at low power.

The switchblade mechanism is of similar technical complexity as a gear retraction mechanism and in itself adds very little weight to SkyCruiser and SkyProwler.

 

Multi-Mission Versatility

SkyProwler can be reconfigured to fly without wings. You can simply take the wings off and fly SkyProwler more like a traditional multirotor. This makes it a slower aircraft with less range and endurance. But it makes it smaller and hence more suitable for small spaces, it makes it less susceptible to cross wind while hovering and it adds duration to its hover time because without wings the aircraft is lighter.
