Uniformed Services Portal - Spectre-1
Specialists from the Warsaw company Spectre Solutions, together with the team of the Faculty of Mechanical, Energy and Aviation of the Warsaw University of Technology, have constructed a universal unmanned aerial vehicle (UAV) for carrying payloads and / or measuring equipment: Spectre-1. It can be used for all kinds of patrol, measurement and transport missions.
The project was implemented with the participation of EU funds under the SG OP measure, the so-called "Fast path". Project entitled "Development and construction of medium and long-range unmanned aerial vehicle capable of transporting cargo or measuring equipment." obtained a grant from the National Center for Research and Development in the amount of PLN 5,031,119.40 (contract number POIR.01.01.01-00-0814 / 17-00).
The main requirements set for the new design were: long operating time in flight, no need to use infrastructure supporting take-off and landing, as well as the largest possible space for cargo or equipment while maintaining the maximum take-off weight (MTOW) not exceeding 25 kg.
The best solution, meeting the requirements, was the combination of the best features of multirotors and airframes in one design. In this way, an aircraft with a fixed airfoil in the classic configuration, but also with a multi-rotor drive was created.
- Thanks to this solution, we have obtained a UAV with the possibility of vertical take-off and landing, similar to multirotors or helicopters, so this drone does not require any additional equipment or infrastructure such as a runway or a launcher - informs Szymon Radtke, President of the Management Board of Spectre Solutions, sp.z o.o. In addition, the drone can hover in the same way as multirotors do. 8 electric motors placed on the drone's beams in the vertical axis are responsible for the implementation of these capabilities. The last, ninth, push engine is used for propulsion in the horizontal flight phase, based on the load capacity of the fixed airfoil.
Two versions of the drone in terms of the push engine have been developed: electric and combustion engine. The use of electric motors only allows to cover a distance of approx. 40 km and to operate UAV for up to 1 hour in flight. In turn, the use of an internal combustion engine as a pushing engine increases the range of the drone to over 150 km and a two-hour flight. The flight is carried out in such a way that the drone takes off vertically and then smoothly switches to horizontal flight. During this period, the boom motors are switched off and the drive is solely via the push motor. Landing a drone is a reverse operation. Before landing, the UAV can hover, thanks to the boom engines, in order to precisely identify the touchdown site.
While maintaining the assumed maximum take-off weight not exceeding 25 kg, it was possible to find a huge space for the load and / or measuring equipment. It is a cuboid with dimensions of 50 cm x 30 cm x 30 cm, which gives a total volume of 45 dm3.
The Spectre-1 drone is equipped with a parachute, which allows the cargo to be safely brought down to the ground in an emergency. This is important when the transport involves specialized and expensive equipment. It should be emphasized that it is a structure with a fixed airfoil, which, in the event of a failure, means that it does not fall to the ground inertia, but descends in a sliding flight, using the lifting force generated by the surface of the airfoil. The measuring equipment is usually located at the bottom of the drones, which in the case of classic multirotors results in its complete destruction in the event of loss of drive or other situation that prevents the drone from remaining in the air. Spectre-1 allows you to equip the transported cargo or apparatus with its own, independent of the main parachute.
The developed UAV implements three flight control modes:
- manual by the operator (also the possibility of alternate control by many operators - switching control between operators),
- semi-automatic by issuing commands by the operator, e.g. end of the mission, fly to the point, hold the ceiling, circle, look around, observe the static point,
- automatic along a given route - completing the mission in contact with the base.
This procedure is implemented only after disconnection and without contact with the base.
Spectre-1 as a universal drone can be used as a carrier of goods and equipment in various areas of the economy, including public safety and monitoring of borders and key roads, aerial photography, crisis management and medical rescue.
Spectre Solutions is not limited to designing and building drones. A team of specialists in cooperation with various centers of Polish science has already developed two specialized measuring devices that can be mounted on the Spectre-1. The first one is used to monitor public roads (motorways and expressways), while the second one is used to very quickly monitor the condition of agricultural crops in a very wide range of lighting and weather conditions. - A solution for automatic battery and charge replacement in the drone is also under development, allowing the implementation of missions that require many hours of flights, without human intervention - adds Szymon Radtke.
In order to be able to deliver larger batches of drones to the market in a short time, Spectre Solutions started the organization of a modern production plant. The Spectre-1 drone will be available to customers at the turn of the third and fourth quarter of 2021.
