Changes: Cochrane (unit)

Revision as of 11:17, 7 July 2007

A cochrane (symbol c) is the unit for subspace distortion, named after Zefram Cochrane, the inventor of warp drive. One cochrane is equal to the force required to establish a field for warp 1. (TNG: "Remember Me") The fluctuation found in subspace distortions are known as the Cochrane distortion. (TNG: "Ménage à Troi")

Millicochrane = 1 one-thousandth of a cochrane

A sign in Doctor Paul Manheim's laboratory on Vandor IV stated that Federation Science Council Regulation 5244 had to be observed at all times when the faciliy was in use, further regulating that all operational equipment had to be rated for 24 mili-cochranes or greater. (TNG: "We'll Always Have Paris")

Several signs with this warning were seen close to the antimatter storage in the lab. The text was not legible on screen though.

When the USS Enterprise-D was hit by a quantum filament in early 2368, it experienced a "+39.1 millicochrane containment field transient event". (TNG: "Disaster")

A transwarp distortion was registered by the USS Enterprise-D at 51 millicochranes. (TNG: "Descent")

While conducting repairs, after the Klingons sabotaged the warp drive of the Enterprise NX-01, locking the ship in at warp 5, the ship's field variance was at 87 millicochranes. (ENT: "Divergence")

A geodesic fold created an output of verteron energy of 408 millicochranes. (VOY: "Inside Man")

Federation Type-15 shuttlepods were equipped with two long-range 750 millicochrane impulse drive engines. (TNG: "Descent")

Federation short-range shuttcraft are powered with two 1,250 millicochrane warp engines. (TNG: "The Outcast")

A graphic of the warp bubble in which Beverly Crusher was caught in 2367, revealed that it had a scan enhancement of 2,058 millicochrane FFT. (TNG: "Remember Me")

Wesley Crusher's static warp bubble was roughly stable at 1,283 x 3,695 millicochranes. (TNG: "Remember Me")

The metaphasic shield employed aboard the USS Enterprise-D in early 2370 had a field distortion of 4,513 millicochranes. (TNG: "Descent, Part II")

The anti-time subspace distortion that appeared in the Devron system had a distortion in the range of 4,077,000 millicochranes. (TNG: "All Good Things...")

4077 is apparently a reference to M*A*S*H.

Cochrane

After B'Elanna Torres had removed nearly all Borg technology from the warp core of the USS Voyager in early 2374, the matter-antimatter reaction was measured at 22 cochranes and rising. (VOY: "The Gift")

A new plasma-dyne relay that Geordi La Forge created in late 2370 was able to withstand over 500 cochranes of warp field stress. (TNG: "Journey's End")

A technique tested by Dr. Lenara Kahn used for creating artificial wormholes in 2372, required the USS Defiant to generate a subspace tensor matrix in the 25,000 to 30,000 cochrane range, and then sending out a magneton pulse using a target drone. (DS9: "Rejoined")

Teracochrane = 1 trillion cochranes

The opening of a Borg transwarp conduit produces subspace disruptions with a field magnitude above 2.9 teracochranes. (VOY: "Dark Frontier")
Tri-cobalt devices used by the USS Voyager to destroy the Caretaker's array in 2371 had a yield of 20,000 teracochranes. A cochrane distortion of this scale is large enough to create a subspace tear. (VOY: "The Voyager Conspiracy")
