Jetpacks

I would rather have a jet bike to be honest. Yes a Jet Bike means finding somewhere to park it but a jet bike does mean faster and with less risk of setting fire to yourself with rocket fuel.

Who's to say it's faster?

Larger vehicle = more space for fuel = more fuel for greater acceleration..? :confused:

I posted an article about a working Jet bike back on my facebook wall some time ago. Yes, it was on IGN lol.

Now the article in the above link says that the bikes have been tested at speeds of around 30mph that's 26.07 knots. It also states that one of the jet bikes can fly at speeds comparable to a helicopter. So I did a bit of quick Googling...

With the technological advances we have seen over the last 25 years, it's fair to say that the average, modern-day helicopter will probably cruise somewhere between 120 knots (222kph / 138mph) and 140 knots (260kph / 161mph).

However, the fastest helicopter remains the Westland Lynx . . . which set the helicopter speed record on 11th Aug 1986 (yeah - 21 years ago!!) It flew at a speed of 216 knots (400.87kph / 249.1mph) in level flight - something that has still not been beaten.

I'd say that's pretty spectacularly accurate since the guy posted sources and is claiming he flies them for a living. Now, he's saying the average helicopter flies at around 120 knots (138 MPH) - 140 knots (161 MPH) so essentially one of these jetbikes in my link would be capable of flight at these speeds. Now consider ease of steering, comfort involved and the fact that whilst the speed may be lower than that of a rocket pack if you were to accelerate from 10000ft - ground level that we are talking about a VTOL bike what doesn't require a parachute for a safe landing or a plane to get it up to height. If we're talking the sort of Jetpack a-la James Bond or Kick Ass then we're talking about a VTOL unit which would not maintain a high speed for long due to the lack of fuel it would carry and also the restrictions of the human body.

Therefore if we factor re-fuelling stops and distance travelled in to the equation I would definitely argue that my jet bike has a far superior speed and range to your jet packs.

It was probably there in the link somewhere (or maybe I missed it in your post) but did you indicate how fast an actual jetpack has been theorized to travel.

I didn't do research on that but it appears with a quick google search that: The "Martin Jetpack" will do an estimated 60mph or 52 knots at an altitude of 8000 ft and fly for 30 mins on a fuel tank load.
