Stephen Bluestone January 31, 2008 Propulsion – Propellants Initial Rocket Sizing Research help from: Dana Lattibeaudiere and Nicole Wilcox AAE 450 Spring 2008

Particulars of Sizing Code § Inputs – User: Propellant/Stage, Payload Mass, Inert Mass Fraction/Stage, (Stage Delta. V %) – Auto: Delta. V, Avionic Mass/Stage, Isp-costdensity/Propellant § Outputs – Propellant Mass/Stage, Delta. V %/Stage, Stage Mass, Stage-Total Cost (Volume/tank) AAE 450 Spring 2008 Propulsion – Propellants

Example of Input and Output The total mass of the first stage is : 10547. 88 (kg) The total mass of the second stage is : 5600. 05 (kg) The total mass of the third stage is : 277. 53 (kg) The total mass of the rocket is : 16425. 47 (kg) The first stage runs for 20. 00 % of the Delta V The second stage runs for 41. 36 % of the Delta V The third stage runs for 38. 64 % of the Delta V The mass of the propellant of the first stage is : 10175. 89 (kg) The mass of the propellant of the second stage is : 4843. 49 (kg) The mass of the propellant of the third stage is : 249. 60 (kg) The total mass of the propellant is : 15268. 98 (kg) The cost of the propellant in stage one is : $ 19639. 47 The cost of the propellant in stage two is : $ 9347. 93 The cost of the propellant in stage three is : $ 481. 73 The total cost of propellant is : $ 29469. 13 AAE 450 Spring 2008 Propulsion - Propellants Code by Stephen Bluestone and Nicole Wilcox
