FOREWORD:

• This Saturn IB Flight Manual provides launch vehicle systems descriptions and predicted performance data for the Skylab missions. Vehicle SL-2 (SA-206) is the baseline for this manual; but, as a result of the great similarity, the material is representative of SL-3 and SL-4 launch vehicles, also.
• The Flight Manual is not a control document but is intended primarily as an aid to astronauts who are trairing for Skylab missions. In order to provide a comprehensive reference for that purpose, the manual also contains descriptions of the ground support interfaces, prelaunch operations, and emergency procedures.
• Mission variables and constraints are summarized, and mission control monitoring and data flow during launch preparation and flight are discussed. This manual was prepared under the direction of the Saturn Pro- gram Engineering Office, PM-SAT-E, Marshal Space Flight Center, Alabama 35812.

SKYLAB PROGRAM:

•  The two-stage. liquid-propellant Saturn IB launch vehicle (figure 1-1) is utilized in the Skylab program to transport the three-man crews to the Saturn Workshop (SWS) in earth orbit. Objectives of the Skylab program are to establish an experimental laboratory in earth orbit and to conduct medical, scientific, and solar astronomy experiments.
• The laboratory. SWS. includes an orbital workshop (OWS), which is a modified S-IVB stage: a mul- tiple docking adapter (MDA): an airlock module (AM): an apollo telescope mount (ATM); and a payload shroud, which is jettisoned during launch.
• The SWS will be launched and inserted into orbit (figure 1-2) from LC-39A at KSC as part of vehicle SL-L., which utilizes a two-stage Saturn V launch vehicle. Approximately 24 hours later, a manned command and service module (CSM) will be boosted into a rendez vous phasing orbit from LC-39B aboard vehicle SL-2, which utilizes two-stage Saturn IB launch vehicle SA-206.
• After rendezvousine and docking with the SWS the crew will activate and inhabit the SWS for a period of up to 28 days and then return to earth via the CSM. On Skylab missions SL-3 and SL-4. launch vehicles SA-207 and SA-208 will place CSM’s into orbit for revisitation of the SWS for up to 56 days on each mission.
• After a pitch and roll maneuver, initiated 10 sec after liftoff, the launch vehicle will fly a time-tilt program that provides near zero angle of attack through the high dynamic pressure region of flight until about 2 min 10 sec after liftoff.
• This attitude will be maintained through S-IB/S-IVB separation at 2 min 22.9 sec after liftoff, until iterative guidance is initiated at 2 min 50 sec after liftoff. During this time period, the expended ullage rockets are jettisoned at 2 min 34.9 sec.
• The launch escape tower will be jettisoned by astronaut command about 23.5 sec after S-1B/S-IVB separation. In the iterative guidance mode the S-IVB pitch and yaw attitude commands are issued to obtain an optimal path (that which requires the least propellant consumption) to achieve the desired end conditions of fight.
• Guidance cutoff signal is predicted to occur at 9 min 50.1 sec after liftoff The S-IVB/IU/CSM will be inserted into an 81 by 120 NM elliptical orbit inclined 50 deg to the equator, at 9 min 60.1 sec after liftoff The CSM will separate from the S-IVB at six min after orbit insertion. At 15 min after insertion. S-IVB tank venting will com mence to passivate the S-IVB. Pressure sphere safing will be ini tiated at approximately 1 hr 23 min after insertion.
• At approximately 36 min after orbital insertion for SA-206, the S-IVB/IU will begin maneuvers to maintain a sun-vehicle orienta tion in support of Skylab experiment M415 for the remainder of the mission. The SA-208 S-IVB/IU will perform attitude maneuvers
