Helicopter Aerodynamics, calculating thrust loading, disk loading, power loading return to the flight school home page Below, we will demonstrate a method to calculate the theoretical thrust that that a propeller or rotor can generate. Of course in a helicopter, the rotor disk is oriented such that we call its force "lift" rather than thrust, "thrust" would be used in the case of an airplane. On a helicopter, the force of a tail rotor would be best described as thrust. The first step is to measure the diameter of the rotor or propeller and calculate the area in square feet. Area is defined as:
Surveillance drone industry plans PR effort to counter negative image An aerial surveillance drone. Photograph: John Giles/PA Companies seeking to enable the routine use of surveillance drones across Britain are planning a long-term public relations effort to counter the negative image of the controversial aircraft. The Unmanned Aerial Vehicle Systems Association (UAVSA), a trade group that represents the drone industry to the UK government, has recommended drones deployed in Britain should be shown to "benefit mankind in general", be decorated with humanitarian-related advertisements, and be painted bright colours to distance them from those used in warzones, details from a UAVSA presentation show. Plans are also under way to establish corridors of segregated airspace to fly drones – or UAVs – between restricted "danger zones" (airspace where test flights take place) in isolated parts of England and Wales.
Pentagon invests $10M to make this scary robot silent and bulletproof A diagonal two beat gait, in quadrupeds, is called an amble. It's the most efficient gait for distance. That's what gaited horses and elephants use to cover huge spans of terrain. Although, would that really matter for a robot? Kinect-carrying drone automatically builds 3D maps of rooms Google Street View eat your heart out: An MIT-built quadrocopter uses Microsoft Kinect, and some smart odometry algorithms, to fly around a room and spit out a 3D map of the environment. The drone itself is a lightweight UAV with four rotors, an antenna, protective and stabilising shielding and the guts of a Kinect sensor. It communicates with a nearby laptop, but all sensing and computation to determine position is done onboard an internal computer. The quadrocopter runs an MIT-developed real-time visual odometry algorithm to work out location and velocity estimates, which helps stabilise the vehicle during its fully autonomous 3D flight.
FastRunner FastRunner is a new bipedal platform inspired from the fastest biped animals, and developed at IHMC. A novel leg design is being developed to enable FastRunner to achieve unprecedented efficiency and speed while being self-stabilizing. The FastRunner project is funded by the DARPA agency through the Maximum Mobility and Manipulation (M3) program. The Team: The FastRunner project is led by IHMC under the supervision of Dr. Jerry Pratt and Dr. Compact Radial Engines MZ 34 engine updates A new set of redrive, redrive plate and a cylinder head have been introduced. → more... MZ 34 new exhaust is now here New chromed look improves longevity and adds on to aesthetics of the motor. → more... The Future of Drone Warfare Over half of Air Force UPT (undergraduate pilot training) grads are now assigned to pilot drones rather than a real aircraft.* The big question is why are drone pilots, guys that fly robots remotely from a computer terminal, going to a very expensive year of pilot training? I can understand why the Air Force has chosen to send drone jockeys to pilot training: A shift to piloting drones rather than real aircraft is an assault on organizational culture of the Air Force.
Robots to get their own internet 9 February 2011Last updated at 10:54 By Mark Ward Technology correspondent, BBC News RoboEarth could help robots get to work in novel environments much more quickly Robots could soon have an equivalent of the internet and Wikipedia. European scientists have embarked on a project to let robots share and store what they discover about the world. Called RoboEarth it will be a place that robots can upload data to when they master a task, and ask for help in carrying out new ones. Quadcopters Make 3D Scans Of Historic Buildings The heck with cranes and scaffolds, the University of Granada is using quadcopters to shoot images of historic buildings and digitize them to 3D. Humans continue to make their lives easier with drones. Small-sized unmanned aerial vehicles (UAVs) are already chasing after wanton criminals, inspecting contaminated power plants, even bringing us our order of delicious tacos.
