Transcript of Quadcopter
Our weekly report
1- the history o quadrotor development
2- parts of final selection as an optimum design for best performance
3- total body design with stress analysis
4- our upcoming goals
Parts selection and main frame design
1- main frame
Convertawings Model A Quadrotor (1956):
This unique helicopter was intended to be the prototype for a line of much larger civil and military quadrotor helicopters. The design featured two engines driving four rotors through a system of v belts. No tailrotor was needed and control was obtained by varying the thrust between rotors.
In the last few decades, small scale Unmanned Aerial Vehicles (UAVs) have become more commonly used for many applications. The need for aircraft with greater maneuverability and hovering ability has led to current rise in quadcopter research. The four-rotor design allows quadcopters to be relatively simple in design yet highly reliable and maneuverable. Cutting-edge research is continuing to increase the viability of quadcopters by making advances in multi-craft communication, environment exploration, and maneuverability. If all of these developing qualities can be combined together, quadcopters would be capable of advanced autonomous missions that are currently not possible with any other vehicle.
Our next meeting objectives
1- we aim for finishing our main frame by next week
2- also sustain some calculations on lift and drag for our module
3- our parts will be delivered if we are lucky enough
4- schedule our plan of building our quad for the next week
Flown successfully many times in the mid-1950s, this helicopter proved the quadrotor design and it was also the first four-rotor helicopter to demonstrate successful forward flight. Due to a lack of orders for commercial or military versions however, the project was terminated. Convertawings proposed a Model E that would have a maximum weight of 42,000 lb (19 t) with a payload of 10,900 lb (4.9 t) over 300 miles and
at up to 173 mph (278 km/h).
The largest use of quadcopters has been in the field of aerial imagery although, in the USA, it is currently illegal to use remote controlled vehicles for commercial purposes. Quadcopter UAVs are suitable for this job because of their autonomous nature and huge cost savings. Capturing aerial imagery with a quadcopter is as simple as programming GPS coordinates and hitting the go button. Using on-board cameras, users have the option of being streamed live to the ground. Many companies have used this for real estate photography to industrial systems inspection. Various organizations are taking advantage of the quadcopter’s closed-circuit television capabilities and ability to provide an eye in the sky to the action below
Design and development
AeroVelo, a team of students and graduates of the University of Toronto, began flight testing its Atlas quad rotor HPH on 28 August 2012. The core team of AeroVelo is the same group who created Snowbird, the first successful human-powered ornithopter. The Atlas is the largest HPH ever flown, and has a tip-to-tip rotor span of 154 ft (47 m), second only to the Russian Mil V-12
it will be a total aluminum + shaped frame
