A Ballistic Missile Primer
A BALLISTIC MISSILE PRIMER Steve Fetter The Rocket Equation Consider a single-stage rocket with a lift-off mass Mlo and a burn-out mass Mbo. In the absence of gravity and air resistance, the change in the rocket's velocity from lift-off to burn-out (the "delta-v") is given by " Mlo % !v = ve log e $ ' (1) # Mbo & where ve is the exhaust velocity of the propellant. If the rocket has n stages, the total delta-v of the rocket is given by n # M & !v = !v + !v + """ + !v = v log lo (2) t 1 2 n ) ei e % ( i=1 $ M bo 'i th where vei is the exhaust velocity of the i stage and (Mlo/Mbo)i is the ratio of the rocket mass when the ith stage ignites to its mass when the stage burns out. The mass ratio of the ith stage is given by ! $ M + M + ''' + M + m ( M (1( s ) M (1( s ) M bo t1 t2 ti p pi i pi i # & = = 1( i (3) " M lo % M t + M t + ''' + M t + mp i 1 2 i M + m ) t j p j=1 where M is the propellant mass in the ith stage, s is the fraction of propellant in pi i th th the i stage that remains unburned, M ti is the total mass of the j stage before it is ignited, and mp is the mass of the rocket payload. The unburned fraction is very low in modern boosters (e.g., s = 0.0012 in the Minuteman-II first stage) and can therefore usually be ignored. -

<> CRONOLOGIA DE LOS SATÉLITES ARTIFICIALES DE LA
1 SATELITES ARTIFICIALES. Capítulo 5º Subcap. 10 <> CRONOLOGIA DE LOS SATÉLITES ARTIFICIALES DE LA TIERRA. Esta es una relación cronológica de todos los lanzamientos de satélites artificiales de nuestro planeta, con independencia de su éxito o fracaso, tanto en el disparo como en órbita. Significa pues que muchos de ellos no han alcanzado el espacio y fueron destruidos. Se señala en primer lugar (a la izquierda) su nombre, seguido de la fecha del lanzamiento, el país al que pertenece el satélite (que puede ser otro distinto al que lo lanza) y el tipo de satélite; este último aspecto podría no corresponderse en exactitud dado que algunos son de finalidad múltiple. En los lanzamientos múltiples, cada satélite figura separado (salvo en los casos de fracaso, en que no llegan a separarse) pero naturalmente en la misma fecha y juntos. NO ESTÁN incluidos los llevados en vuelos tripulados, si bien se citan en el programa de satélites correspondiente y en el capítulo de “Cronología general de lanzamientos”. .SATÉLITE Fecha País Tipo SPUTNIK F1 15.05.1957 URSS Experimental o tecnológico SPUTNIK F2 21.08.1957 URSS Experimental o tecnológico SPUTNIK 01 04.10.1957 URSS Experimental o tecnológico SPUTNIK 02 03.11.1957 URSS Científico VANGUARD-1A 06.12.1957 USA Experimental o tecnológico EXPLORER 01 31.01.1958 USA Científico VANGUARD-1B 05.02.1958 USA Experimental o tecnológico EXPLORER 02 05.03.1958 USA Científico VANGUARD-1 17.03.1958 USA Experimental o tecnológico EXPLORER 03 26.03.1958 USA Científico SPUTNIK D1 27.04.1958 URSS Geodésico VANGUARD-2A -

South Africa Missile Chronology
South Africa Missile Chronology 2007-1990 | 1989-1981 | 1980-1969 | 1968-1950 Last update: April 2005 As of May 28, 2009, this chronology is no longer being updated. For current developments, please see the South Africa Missile Overview. This annotated chronology is based on the data sources that follow each entry. Public sources often provide conflicting information on classified military programs. In some cases we are unable to resolve these discrepancies, in others we have deliberately refrained from doing so to highlight the potential influence of false or misleading information as it appeared over time. In many cases, we are unable to independently verify claims. Hence in reviewing this chronology, readers should take into account the credibility of the sources employed here. Inclusion in this chronology does not necessarily indicate that a particular development is of direct or indirect proliferation significance. Some entries provide international or domestic context for technological development and national policymaking. Moreover, some entries may refer to developments with positive consequences for nonproliferation 2007-1990 26 April 2007 The state-owned arms manufacturer Denel Group has signed a 1 billion rand (143 million U.S. dollars) deal with Brazil to co-develop a new generation missile. The missile will be the next-generation A-Darter, and air-to-air missile designed to meet future challenges of air combat fighters. The partnership will Brazil will bring "much needed skills, training and technology transfer to the country." Furthermore, future export contracts of another 2 billion rand are expected in the next 15 years. — "S.
