Denel Aerospace has introduced a new Rotary Wing Unmanned Aerial System (RW-UAS)
as part of its product diversification strategy. This innovative drone is designed
primarily for [surveillance purposes](https://www.military.africa/2022/06/south-africa-military-drones-unmanned-aerial-vehicles-uavs/),
providing situational information and detailed object or terrain data.

According to _defenceWeb_, years ago, Denel collaborated with local universities
and Armscor to develop next-generation aircraft, including an unmanned helicopter(
Prowler) and a manned airplane (Small African Regional Aircraft – SARA). The RW-
UAS, a result of this research, operates day and night, equipped with optical sensors
and an optional radar sensor. Standard sensors include a thermal imaging camera,
high-definition color TV camera, auto tracker, laser rangefinder, and designator.
Optional radar capabilities include synthetic aperture radar (SAR) and inverse synthetic
aperture radar (ISAR) imagery, as well as ground moving object indicator imagery.

The RW-UAS features automatic vertical take-off and landing and can operate autonomously
with a 10-hour endurance carrying the standard payload. With an additional 80 kg
payload, it can fly for four hours. The maximum take-off weight is 560 kg. Its fully
articulated five-blade main and tail rotor system ensures a low noise profile, allowing
operation from various landing zones, including vehicles and vessels.

With an airframe length of 5.9 meters, a rotor diameter of six meters, and a height
of 1.7 meters, the RW-UAS is powered by a 4-cylinder, 4-stroke turbocharged petrol
or diesel engine, reaching speeds of up to 200 km/h. Its applications include law
enforcement, public safety, border patrol, wildlife monitoring, area surveillance,
powerline inspection, disaster management, search and rescue, communications relay,
and geological surveying.

The RW-UAS offers multiple flight modes, including Autonomous mode with autopilot
control for pre-planned flights, Trajectory mode with autopilot executing commands
from the Ground Control Station (GCS), and a sense and avoid capability. In the 
event of a communication failure, the system autonomously flies to a predetermined
landing point. It also has provisions for engine rotor failure, allowing for autorotation
and autonomous landing.
