I must have, flying bike

[look 171]

Flying bike completes its first test flight. [VIDEO]

I gotta have one of these. How legal is it to fly one of these thing around in traffic? Since, you are not technically on the street (10-12 feet above everyone else), can they ticket you?

No more dealing with mad traffic for me.

Only if the cop is on stilts.....duh.

[Schumi]

this one has way more style.... I saw it a few years back and still hope it is being worked on ...

That's awesome. I notice it is displaying a beacon - I'm guessing this falls under FAA jurisdiction (ultralight aircraft perhaps? If so, no using this in/near major cities). I suspect the federal, state and local regulations that would apply to this thing would make it frightfully expensive and impractical to ever operate. Not to mention the liability insurance cost.

Damn cool invention. A shame our governmental bureaucratic quagmire will kill it. It'll probably end up getting used in a big way in China and Mexico in a few years though - places that have a more sane approach to governance.

Yea, that will work great until a gust of wind from a passing simi slams you in a tree.

It will go nowhere, period, full stop. So sayeth physics.

Carrying enough stored energy to keep the thing aloft for more than a few minutes, means too much weight to make it a usable bicycle.

I suspect the "bicycle" and "rider" shown in the video are ultra-light dummies.

The Martin Jetpack uses a 2 liter gas engine, and even then is too large to walk with and can only stay up for 30 minutes. Supposedly. Development seems stalled since 2011.

Read here - go to "news" and look at the still pictures and the video

The "rider" is a dummy, and looks very lightweight.

The "bike" is basically a frame stuffed with LiPo batteries, with wheels at either end.

I'm going to guess that dummy plus the "bicycle" specific components (wheels, fork, pedals, handlebar, saddle, etc) weigh 30 lbs.

So basically, the lesson is that a 15 foot long electrically powered helicopter can carry a payload of 30 lb for a couple of minutes.

Impressed?

I would not want the general public to have access to something like that.

The dynamics of operating a vehicle whose thrust is not delivered mechanically are likely too much for the average person.

Engine braking is something most people don't even think of but it happens every time you lift the loud pedal.

Anything that flies does not deal well with panic stops unless you count falling out of the sky stopping.

I will wait for the stealth version.

Flying Bicycle Achieves Liftoff in Prague - ABC News

F-bike flies not with wings but with six motorized propellers attached to the bike's frame: two propellers in the front, two in the back, and one on each side of the seat.

Nice sized R/C model which inspires the imagination.

The Basic Parameters of the Flying Bike
total output: 54 kW
drive: 4× main motor 10 kW, placed in opposed pairs at the front and at the back in a longitudinal axis; 2× stabilisation motor 7 kW, placed on turnable consoles at the sides of the bike
propellers: the main propeller diameter 1200 mm, maximum revs 2200/min, stabilisation propeller, diameter 650 mm, the propellers are surrounded by composite casings
energy: set of Li-Pol accumulators with total capacity 50 Ah
frame of the bike: welded part made of light alloy (duralumin)
bike components: purchased in a standard way
dimensions: approx. 3800 mm (length) × 2500 mm (width) × 1200 mm (height)
weight: 95 kg without a pilot
maximum laden weight: 170 kg
supposed flight time: 5 minutes
supposed riding time: 30 – 50 minutes
maximum speed limit: 50 km/hour

I still want my flying car. In the 60s they said it would happen by the year 2000!

If the bike's wheels were spinning fairly fast, would that create a beneficial gyroscope effect?

I don't think so. I'm not an aerospace engineer nor a physicist, but I would think that gyros big enough to produce a noticeable effect would not produce a beneficial effect. I suspect it would make handling counter-intuitive since the airbike theoretically has three axes of rotation (as opposed to a bicycle with only one).

Gyros (or motion sensors) in modern systems are used to detect attitude changes not resulting from user input, which are then fed back into the control system to make corrections. You don't need big gyros for this.

That is funny and correct. The below is called the, "Wheel of Misfortune" in the aero and aircraft design world:


The chart basically covers every STOL and VTOL concept ever designed. They ALL have issues

Piasecki, a company I have worked with for years called it the Geep:

Well, fast spinning bike wheels do resist being moved in the other 2 axes which would be what, roll and yaw? Anyway and otherwise, why have vertical wheels? That thing would be a beast to ride on the ground. And they don't seem to aid in landing.

The whole idea is stupid.
