After six years in production, the new Watupá UAS 2018 reaches an almost perfect combination of payload capacity, flight stability and endurance for large-area SUAS operations.
This new version has the sturdiness and reliability of our former fuel-engined Watupá, now with an electric power plant, as used byour (now deprecated) ergonomic Hewë an Siemari electric flying wings. Hewë was an excellent product for small-size operations, and Watupá was a sturdy entry-level UAS. The new Watupá sinthesises all of them in a new concept.
After two years of design improvements and tests, even working with a new tractor engined flying wing, code-named 'Flying Toad', and several fixed wing Watupá fuel-engined variants, we arrived to this new design, offering sturdiness, easy to use, long endurance, precise flight with very high transversal wind resilience, at a low cost of operation.
This SUAS with power-glider-looks, achieves its high aerodynamic efficiency and endurance through its high aspect ratio wing concept and a V-tail configuration.
This new Watupá addresses requests from customers and partners (mostly) from South America and Africa, using SUAS (from different shapes and vendors) for a solution to fly over large areas in one single flight (thousands of hectares, not just simple orchards) with the easiness of an electric foam flying wing.
It is not only that small foam flying wings are fragile and not able to cover large areas for lack of autonomy. They also demand complex logistics, moving ground operations around to cover a large area through multiple flights, loosing time and increasing logistics costs. Worst off, small foam flying wings give low quality images (blurred) with lower precision when flying above ~20-30m height over areas larger that a 5-10 hectares. This is because of transversal winds an vertical turbulences. Hewë didn't suffer as much because of its composite airframe, but flight efficiency was more adequate for Europe or California that to fly over the huge agriculture plantations, forestry plots or tropical forests of South America, Africa or South East Asia.
Watupá is designed for easy assembly, with the sturdiness for hard belly landing as a simple flying wing, and also withstand adverse weather conditions as a bigger fixed wing UAS, operating for longer periods with a stable flight behaviour.
