More Info
[edit]This Flight Int article might be of help. It probably repeats much of Reaction Engine info, but has comments from ESA’s LAPCAT coordinator. -Fnlayson 01:29, 5 September 2007 (UTC)
Hahaha!!!!
[edit]It looks exactly like the Myasishchev M-50!!!!!
- Only superficially. Tail's different. Wings are smaller. There's no cockpit at the front, fuel is different. Top speed is much higher. There are many other differences, and I highly doubt that the current artist impression would look anything like the final flight article.- (User) WolfKeeper (Talk) 14:22, 1 September 2008 (UTC)
Isp or exhaust velocity are not well calculated
[edit]We can read "effective exhaust velocity of 40,900 m/s or specific impulse of 4170 s". That would be right for a rocket, but for an air breathing engine, the Isp is not calculated from Isp=Ve/9.81 — Preceding unsigned comment added by Cometo22 (talk • contribs) 12:38, 20 April 2015 (UTC)
