Polish counterpart of Outback Challenge: MIWL Bezmiechowa 2010 (7th edition)

Even if there is no webpage in english, you might enjoy browsing the polish version.
There are 4 participants with quite interesting UAVs.
AFAIK they were stabilized FPV planes in 2009 with onboard autopilot prototypes made by the students.

Current constructions are:


Rzeszów University of Technology
PR-5+ Wiewiór

(Wiewiór=male squirrel, probably the one from Ice Age Cartoon, watch the nose...)

(see picture above)

Wiewiór, following my imagination:



Catapult testing:



Warsaw University of Technology
Adeli 2 http://aerodesign.meil.pw.edu.pl/uav/

Bialystok University of Technology

Maiden flights (sort of Delivery 1 from Outback challenge)





Wrocław University of Technology
UAV BALSA (in fact made of fiberglass)



Rules (of course in Polish - yes, is profitable to learn Polish in order to follow the most recent developments in avaition technology)

Note: BSL means UAV in Polish.

Almost all entrants have very well engineered platforms made of kevlar, carbon fibrglass, CNC machined metal wing joints, pan-tilt turrets.
Somehow Poles got crasy about bimotor with less or more inverted Vtail plus ailerons.
No landing gears, apaprently no flaps, at elast 2 got parachute since 2 years.
Adeli and Wiewior had their SAE heavy lifter versions.

The mission is similar to Outback challenge in that the main problem is identifying a target position (square cloth). Nothing has to be dropped, the search area is closer, but the landing area is very difficult (must land uphill or between the trees, this is a glider airstrip on mountain slope. Pteryx was there, see the photomap:

Very nice. Been thinking about twin motors on twin boom configuration; I like this one you linked to:
"Maiden: http://www.youtube.com/watch?v=aL1dEbgLxpc"
Nice shots of blue sky and clouds.

Do you know how much it weighs?

They are all limited to <5kg and indeed I believe they are all above 4kg from the amount of internals and batteries in them. In attachment: Adeli1 report from MIWL 2009.
They say: weight:5 kg

Contest regulations say: UP TO 5kg, no exceptions.

We are on DIY Drones - prestige ^^
Adeli2 weights 3.4kg for maiden flight. With avionics, fpv systems, parachute it raises to 4.7kg.
We achive such small weight thanks to moulded parts made of carbon-fiber and stress calculations to minimalize mass.
