Mar 8, 2022 · The drag of a body moving through a fluid is a force, acting in the opposite direction to the motion of the body, and causing a decrease in the velocity of the body. Like lift, drag acts on the center of pressure and is dependent on the shape and size of …

Jun 10, 2021 · It is used to initially size an unmanned aircraft for a typical reconnaissance mission. The improved parasitic drag estimation yields a much heavier unmanned aircraft when compared to the sizing results using available drag data of manned aircraft.

Jan 5, 2025 · Key factors influencing energy efficiency include the drone’s weight, with heavier drones requiring more lift and, consequently, more energy; propeller efficiency, where optimized blade designs minimize energy loss; and aerodynamics, as streamlined frames help reduce drag.

Jan 3, 2023 · The aim of this study was first to investigate the influence of mass and shape on the drag of a quadrotor, and second to propose a method to estimate this drag coefficient from flight data. This parameter is crucial for wind estimation, but …

Drag is the resistance a drone encounters from the air as it flies; minimizing drag is crucial for enhancing efficiency. Drones manipulate these forces through sophisticated propulsion systems and agile design: Fixed-Wing Drones: These drones generate lift through static wings and thrust via propellers or jet engines.

Jul 27, 2023 · An electric consumer drone designed for a very simple mission, with a fixed and constant payload, can probably be brought to market without a profound understanding of its lift and drag curves; after all, its range and endurance could be established simply by flying the vehicle to battery exhaustion in a range of conditions, which would place a ...

Nov 23, 2017 · While the drag of aircraft cruising at low reynolds numbers is relatively well understood, the dramatic increase in popularity of drones has lead to a variety of novel, multifunctional...

Apr 5, 2025 · “Our findings offer valuable data for drone design to allow for handling aggressive maneuvers without excessive drag or loss of control.” Source: “Predicting the high-angle-of-attack characteristics of an airfoil for micro/unmanned aerial vehicle applications,” by V. Somashekar and L. Vinod, International Journal of Fluid Engineering ...

Jun 10, 2021 · The paper presents the derivation of a new equivalent skin friction coefficient for estimating the parasitic drag of short-to-medium range fixed-wing unmanned aircraft. The new coefficient is...

Light-weight models to represent accuratly the physics of forward flight are proposed. One significant finding is that the design opti-mization code enables to rapidly obtain a design for a given set of requirements and has been validated on the Parrot ANAFI USA.
