ARCA, teste UAV Air Strato pe pista inierbata

   Pentru Air Strato, vehiculul electric aerian fara pilot, ARCA a efectuat o serie de teste pe teren cu iarba. Aeronava a fost accelerata pana la viteza de decolare pentru a verifica daca trenul de aterizare este capabil sa ruleze pe acest tip de pista. Am stabilit, de asemenea, distanta necesara de decolare. Air Strato are o viteza foarte mica de decolare, de aproximativ 50 km/h si poate folosi orice tip de pista, inclusiv beton, piste de aterizare de iarba, chiar si piste improvizate acoperite cu noroi. Este propulsat de motoare electrice puternice si decoleaza pe o distanta foarte scurta, de max. 65m. Acest lucru face ca aeronava sa poata fi exploatata in conditii diverse datorita distantei mici de decolare si aterizare, utilizand orice zona de teren disponibil .


"Am rulat treptat, cu viteze mici, pana cand am ajuns la viteza de decolare . Motoarele electrice , in ciuda dimensiunii, sunt foarte puternice si am ajuns de la 0 la 50 km/h in numai 65 m. Pe pista de beton, viteza de decolare a fost atinsa in doar 50m . Nu am instalat inca frane, asa ca din momentul opririi motoarelor pana in momentul opririi aeronavei a trecut ceva timp. Pista de decolare a fost improvizata prin curatirea zapezii si nivelarea usoara a solului, dar am nu a facut mai mult . In general , suntem impresionati de cat de bine a functionat aeronava . "

 Dumitru Popescu , presedinte ARCA .


Air Strato este un vehicul aerian de mare altitudine, fara pilot, alimentat electric. Poate atinge altitudini de 18 km si are o autonomie de 7 ore cu acumulatori interni si trei zile, folosind panouri solare. Poate transporta o sarcina utila de 30 kg, constand in echipamente de supraveghere sau alte instrumente stiintifice. O versiune comerciala va fi disponibila pentru achizitie.

ARCA, Air Strato UAV tests on rough ground

ARCA performed a series of tests on rough ground for the Air Strato electrical powered unmanned aerial vehicle. The aircraft was accelerated to take-off speed to verify if the landing gear is able to hold on this type of runway. We also determined the required take-off distance. Air Strato has a very low take-off speed of about 50 km/h and can use any type of runway, including concrete, grass landing strips, even improvised runways covered with mud. The powerful electrical motors propel it to take off speed in a very short distance of max. 65m. This makes the aircraft able to be operated in a variety of conditions and the low take-off and landing distance make it possible utilise any flat strip of land available.

"We started with low speeds passes and gradually increased until we reached take-off speed. The electrical engines, in spite of there sizes, are very powerful and we reached 0 to 50 km/h in only 65 m. On concrete, the take-off speed was reached in only 50m. We haven't installed wheel brakes yet so it took a while to come to a stop after engine cut-off. The runway was improvised by clearing the snow and leveling the ground a bit, but we didn't do much more. Overall we are impressed on how well the aircraft performed." said Dumitru Popescu, ARCA president.

Air Strato is a high altitude electrical powered unmanned aerial vehicle. It can reach altitudes of 18 km and has an autonomy of 7 hours on internal batteries and 3 days using solar panels. In can carry a payload of 30 kg consisting of surveillance equipment or other scientific instruments. A commercial version will be available for purchase. In Romania it will be available to private individuals and enterprises only.

ARCA is developing a high performance unmanned aerial vehicle

The aircraft is named Air Strato and is part of a larger UAV family that will carry out various missions for ARCA and our partners. The first prototype is completed and is already in testing. This is the largest version having a wingspan of 16m (52 ft) and is intended for stratospheric flights up to an altitude of 18 km. The aircraft is electrically powered and has autonomy of 7 hours on internal batteries and 3 days using solar panels. It can carry a payload of 30 kg consisting of aerial photography and surveillance equipment, scientific instruments or other payloads for various tasks including additional battery pods for extended autonomy. The other versions of Air Strato have a smaller wingspan and lower flight ceiling but higher maximum speed and larger payloads.

"Our activity requires that we perform stratospheric missions for our partners and clients, and solar and helium balloons we used until now, although capable of lifting heavier payloads to higher altitudes, are more expensive and time consuming in construction, are dependent on calm weather conditions and require aerial safety zones to be established. Air Strato can fill their roles much cheaper and reliable for an extended period of time and perform additional tasks for clients such as surveillance over a fixed area, telemetry testing and scientific experiments for extended period of time or other missions. It will make our entire aerospace activity much easier and less expensive." Dumitru Popescu, ARCA, CEO.

If tests are successful ARCA is considering developing commercial versions of Air Strato and other UAV in the family.
