for use in military, law enforcement, border security and emergency services, as well as food security, asset inspection and search and rescue.in Kursk Oblast in western Russia on August 27. The attack damaged a Mig-29 and four Su-30 fighter jets, two Pantsir anti-aircraft missile launchers, gun systems, and an S-300 air surface-to-air missile defence system.
Generally, small drones offer high-resolution imagery for reconnaissance in a rapidly changing theatre of war. The Corvo drone has a high-resolution camera that provides images covering a large area, transmitting footage back to its user in real time. The importance of real-time mapping is critical in modern agile armed forces’ command and control as this can direct ground forces, heavy weapons and artillery.In some cases, the design of small drones is concentrated on adapting the payloads to carry different types of munitions, as seen in the attack in Kursk.
The cardboard drones can carry 5kg of weight, have a wingspan of two metres and a range of 120km at a reported cost of US$3,500 . Waxed cardboard is an ideal material as it offers weather resistance, flat-pack transportation and, importantly, a lightweight airframe, which enables a longer flight range and a high cruise speed of 60km/h.
Fixed-wing drones also offer longer ranges than rotor-based drones as the wings generate the lift and the airframe has less drag, so they are more energy efficient. They can also fly at higher altitudes. The drones can be launched from a simple catapult or by hand and so can be rapidly deployed.Radar involves the transmission of electromagnetic waves, and these are reflected off any object back to a receiving antenna.
