Also, gyrojets figured into the Star Frontiers RPG pretty heavily IIRC. Additionally, while gunpowder would need oxygen to burn, wouldn't gyrojets be able to fire in a vacuum?

Gunpowder doesn't need oxygen to burn. --81.227.115.67 18:56, 12 June 2006 (UTC)

The use of "power" in the following sentence is ambiguous and possibly incorrect.

After about 75 yards (70 m) the motor would burn out, at which point the pistol-sized round had about 50% more power than the common Colt .45.

It is possible the author meant energy, a physical quantity which is surely known for this caliber and should be specified with appropriate units for a range of 75 yards. It is also possible the author meant stopping power. If so, this should be specified more clearly. No other meaning of power is correct or particularly meaningful in the discussion of firearms.

"energy" is what the reference says. Pol098 (talk) 00:54, 9 April 2008 (UTC)

[edit] Tests

Some tests are quoted here: [1]. Muzzle velocity at 1 ft was stated at 105ft/sec, and acceleration about 70 fp/s per foot, implying a muzzle velocity of about 35 fps. But it is misleading to quote muzzle velocity in the summary, as it simply misleads people used to conventional firearms. The topic is discussed in the text. Pol098 (talk) 00:14, 9 April 2008 (UTC)

The figures quoted for the distance at which fuel was exhausted and just about everything else varies between the different references. The 2003 tests seem to have been reasonably well conducted. The sonic boom on about half the shots is a very good indicator of maximum speed (and variability between rounds). Pol098 (talk) 00:54, 9 April 2008 (UTC)
