There still are people who are angry and sad the Atlas V now flies with RD-180 engines.<br /><br />During Constellation there was talk of using upgraded and improved Saturn-derived J-2 engines but that would take so much more time to develop and to get it man-rated.<br />If the U.S. wants to get the first launch somewhere in 2020, they have to use what they have now. Even RD-180s, if they should need it.<br /><br />It's a good thing they are going to salvage the SSME's.Paper Kosmonauthttps://www.blogger.com/profile/14752804726511051169noreply@blogger.comtag:blogger.com,1999:blog-401236675799724196.post-80477593289702294182011-09-14T22:16:11.616+02:002011-09-14T22:16:11.616+02:00Hi Kosmonaut
This is really the "Ares V"...Hi Kosmonaut<br />This is really the "Ares V"? Two SRB +Ares V + "design saturn"<br />engine J2X LOX+lh2 +RS-68 & <br /><br /> RD-180 Энергия engine LOX+kerosine(I've read rumors)<br /><br />SRB change "The blocks of the first stage are ejected in couple from the launcher after having consumed their fuel at 140 s from the ignition, an altitude of 53 km and a speed of 1.8 km/s. Then 15-25 s later they separate individually and 8 min after land in an area located at 426 km of the launch pad. Each block can be equipped with parachutes and retrorockets which settle in the 2 containers parts (in top and bottom) to soften the landing and to allow their re-use. There was a project which envisaged to equip the blocks with retractable wings and automatic landers to enable them to make a self-directed descent and a landing on a runway.<br />The blocks of the first stage are envisaged to be re-used 10 times, the machines and systems of flights 15 times, the engines 27 times.<br />In the first flights the blocks were not equipped with parachutes nor of retrorocket, because the monitoring equipment was installed there."<br /> <br /><br />Merzomerzohttps://www.blogger.com/profile/11204014734167276306noreply@blogger.com
