Hi, We are working on an engine design with peroxide as the cooling agent.
Since in a kero/HTTP engine you have about a 7:1 O/F ratio, there's plenty more HTTP to cool with, i.e. the flow rate is about 7 times larger. The only issues as I see it, is first of all to avoid overheating the HTTP in the cooling channels, as it would start to decompose in the channels, potentially leading to engine blowup. Secondly, you can't use copper or any other material which would cause the HTTP to decompose. On the positive side, you don't have problems with the kero leaving residue inside the cooling channels, i.e. no need for very refined kerosene (eg. RP-1). I believe that the Black Arrow design used HTP for coolant. The chambers were made of steel and aluminum. - Henrik DARK, Denmark -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alexander Mikhailov Sent: 23. januar 2004 11:46 To: [EMAIL PROTECTED] Subject: [ERPS] regenerative cooling with peroxide Hi, is it possible to use peroxide for regenerative cooling of byprop chambers? Say, you have a nice peroxide-kerosine engine, with plenty of HTP in rocket tanks; can you channel the peroxide through the cooling jacket of the engine so that engine won't overheat? How the designers of engines for Black Arrow handled this? Did they use kerosine as the coolant? Thank you, Alexander __________________________________ Do you Yahoo!? Yahoo!
