Saturn H-1 Engine Design Features

David L. Christensen's personal collection includes a memo entitled "Saturn H-1 Engine Design Features." This document, dated 21 September 1959, details features of early H-1 rocket engines, including the engines for use with the SA-T (static test) stage, H-1001 through H-1009.

As an early memo, it discusses a number of matters which never came to be: It refers to the Block I Saturn Is as SA-1 through SA-3, with the Block II vehicles being SA-4 through SA-6 (the Block Is were actually comprised of SA-1 through SA-4, with SA-5 through SA-10 rounding out the Block II vehicles).

It also discusses a later (188,000 pound) block of H-1 engines, referred to as Engine "X". This engine was to incorporate a number of advanced features, including the "desirable features" of the H-2 rocket engine (an engine of which I'd never before heard):

This memo consists entirely of text, without any photos or diagrams.
