wrote: In the past I have heard newsgroup posts about the Titan II first stage, that it had a gross mass of 269,000 lbs and an empty mass of 9000 lbs, which would give it a mass ratio of over 29! See a posting by Mitchell Burnside Clapp at: http://webhome.idirect.com/~earlcp/messages/M1168.HTML halfway down the page. But when I look at Encyclopedia Astronautica at http://www.friends-partners.ru/partn...lvs/titan2.htm I see the gross mass at 117,866 kg (260,000 lbs) and an empty mass of 6,736 kg (14850 lbs), giving a mass ratio of 17.5 So, which is the right value? Thanks, -- Larry According to Don Boelling's Titan II ICBM Web Page: http://home.teleport.com/~boelling/titan.html http://home.teleport.com/~boelling/titanD.html "...Summary Stats length: 103' / 31.3 m diameter: 120" / 3.05 m launch weight: 327,000 lb / 149,700 kg end speed: 24,000 km/h range: 6296 - 8100 nm / 4000 - 15000 km ceiling: about 700 mi. accuracy/CEP: 0.5-0.8 nm..." ..."Some statistics on the Stage I airframe a a. Length-70 feet. b. Diameter-10 feet. c. Approximate weight loaded-258,000 pounds. d. Approximate fuel capacity-84,600 pounds. e. Approximate oxidizer capacity-162,500 pounds...." "...Some statistics on Stage II a a. Length-20 feet. b. Diameter-10 feet. c. Approximate weight loaded-64,000 pounds. d. Approximate fuel capacity-20,700 pounds. e. Approximate oxidizer capacity-37,200 pounds...." Now you probably have three sets of stats for the Titan II. Don Boelling was on a Titan II missile alert crew and then was a Wing Instructor for the 390th Strategic Missile Wing (Titan II's), he instructed missile crews on launch and troubleshooting procedures. I think I would take his figures as fact. -- Rusty Barton - Antelope, California Visit my Titan 1 ICBM History Website at http://www.geocities.com/titan_1_missile |
