Why don't we have low flying vehicles like 'Drone' even for single passenger?
Can we make use of Diffusers/Nozzles in combination with SERVO-Motor operated blowers to attain sufficient LIFT?
I guess the problem is acoustic and the wind disturbance in the low heights as per the civil aviation criteria.
thanks Brijesh Kumar. Anyhow, we have some frequencies declared amateur as per National Frequency Allocation. I believe the toy planes are using that.
Other things come to mind:
- high density of air requires low flight speeds for given power
- gusts lead to low comfort and structural loads
- risk of bird strike with structural damage, ingesntion into propulsion system
- unreliable scheduling due to weather (rain, snow,
- noise (the public would not like it)
- higher crash risk as there is no time to find a suitable emergency landing field
- too many idiots who cannot even drive a car would now be in the air above my head ;-)
Thank you Martin. Could u please tell if we can produce sufficient lift to fly a single passenger by a Quad-copter toy plane type of arrangement? Going by similitude design what would be the expected size?
Mohd,
you shoudl do some research, e.g. by looking at rotor loadings of helicopters. Also check out the E-VOLO vehicle, which shows what size is needed. - Martin
I would like to add few points in addition to Mr. Martin regarding second part of your question. Servo operated micro jets can be used for some sort of spontaneous directional control, dive and climb. But they cannot provide sufficient lift for the aircrafts to sustain the flight during adverse conditions. Every flight has certain flying altitude based on the lift requirements (balance the aircraft) as density (play a role on lift) reduces with increase in altitude. Certainly quad-copter plane will be able to fly with more than one passenger. You need to design (scaled up prototype) the quad-copter (thrust rating) which could able to lift plane with passenger. Presently lot of research is going on aerial robot with quad rotors around the world.
