An revolutionary jet drone, boasting excessive maneuverability, has been patented by the Scientific and Manufacturing Union of Mechanical Engineering, a division of the Russian Navy-Industrial Company. This info is from a TASS company report dated April 28, 2024, which cited the company’s newly issued patent.
The invention pertains to the world of aviation, particularly to unmanned aerial autos [UAVs] of the plane kind. These UAVs are constructed following an built-in association based mostly on the canard stability scheme. With top-flight pace and agility, these drones simply distinguish themselves from their counterparts. The patent summary factors out that “the technical innovation acknowledged beneath goals to boost the flight attributes of UAVs in comparison with their contemporaries.”
The UAV boasts a cargo compartment positioned in its central fuselage. Prime options embrace a uniquely designed wing, a totally movable entrance outfitted with a increase bracket, and a V-shaped vertical tail adorned with trapezoid fins.
Turbojet engine
Because of its distinctive wing form, this drone displays enhanced aerodynamic traits throughout flight, particularly at steeper angles of assault, and it may well additionally successfully counter wave drag. To additional improve the aerodynamic qualities together with take-off and touchdown performances, the wing is fitted with cutting-edge mechanisms at its main and trailing edges.
The turbojet engine, which acts as the facility plant, is positioned uniquely with its air consumption positioned below the fuselage. The drone incorporates an integral format design that makes use of a canard rudder scheme to realize quicker pace and improved maneuverability. This strategy additionally will increase the drone’s lift-to-drag ratio and the utmost elevate coefficient.
Specialists anticipate that, fitted with the suitable tools within the cargo bay, this state-of-the-art drone could possibly be utilized for each reconnaissance and assault missions.
L-shape wing
The L-shaped wings on the drone, additionally known as L-wings, considerably impression the aerodynamic efficiency of the wing, notably throughout high-angle assault flights. The L-wing design is distinguished by a main wing floor extending outward from the fuselage, then bending or ‘sweeping’ backward into an L form. This design proves particularly efficient in enabling high-speed flight and maneuverability.
The L-wing design improves the aerodynamic efficiency by delaying the onset of movement separation. Movement separation happens when the air flowing over the wing floor begins to detach, resulting in a lack of elevate and a rise in drag. When a drone is flying at excessive angles of assault, the chance of movement separation will increase. Nonetheless, the swept-back portion of the L-wing design helps to delay this separation, permitting the drone to take care of elevate and management even at excessive angles of assault.
Lowering wave drag
One other benefit of the L-wing design is its means to scale back wave drag. Wave drag is a type of drag that happens at excessive speeds, particularly close to or past the pace of sound. It’s attributable to the formation of shock waves within the air across the plane. The L-wing design helps to mitigate this by distributing the shock waves alongside the size of the wing, lowering their general impression.
As well as, the L-wing design aids in managing the middle of stress. The middle of stress is the purpose the place the entire sum of a stress discipline acts on a physique, inflicting a drive to behave via that time. Within the case of an L-wing, the middle of stress strikes much less because the angle of assault modifications, offering extra steady and predictable dealing with.
General, the L-wing design on a drone affords vital aerodynamic advantages, notably when flying at excessive angles of assault. It helps to delay movement separation, scale back wave drag, and handle the middle of stress, all of which contribute to improved flight efficiency and management.
