Instrument Unit Checkout

Automated testing and checkout of the Saturn instrument unit at MSFC follows the same general plan as the S-I stage test and checkout. The components and subsystems are thoroughly evaluated prior to assembly into the instrument unit. After assembly, testing of individual components within the instrument unit is performed only to the extent that in-line equipment designs permit identification within each subsystem. For systems tests and over-all tests, instrument unit checkout automatic support...

Sic Stage Implementation

Ordnance on the S-IC stage includes retromotors used during S-IC S-II staging and propellant dispersion system ordnance. 23-23. Retromotors. Eight retromotors, located in pairs in each of the four S-IC engine fairings, provide deceleration of the S-IC stage during separation of the S-IC stage from the launch vehicle. The ignition charge is distributed to two pyrogen initiators in each motor by means of a confined detonating fuse (CDF) train which is connected to a detonator block. Two EBW...

Electronic Bridge Wire Firing Unit EBW Detonators. The EBW detonators are electrically activated devices which rapidly and reliably initiate the explosive leads in the rotor of the S amp A device. Each detonator is fitted with two-pin contacts which serve as mounting posts for the bridgewire assembly inside the detonator . The pins are connected externally to the lead-wire cable of the electronic bridge wire firing unit. When the firing unit is triggered, a high-energy pulse of...

Sib Stage Implementation

Ordnance devices on the S-IB stage include components used for transfer of electrical power, engine starting and cutoff, and propellant dispersion system ordnance. These comporents are similar to those used on the S-I stage of the Saturn I launch vehicle. Refer to Paragraph 9-22. Ordnance on the S-IVB stage includes explosive liftoff switches used during launch Refer to Paragraph 9-23 , ullage motors, retromotors, a mild detonating fuse MDF , and frangible nuts used during separation, and...

Separation System

The primary function of the Saturn V separation system is to provide positive separation of the S-IC stage from the S-II stage, and the S-II stage from the S-IVB stage during the ascent phase of the mission. The following description does not include an explanation of the separation of the S-IVB IU from the Apollo payload during the translunar trajectory phase of the mission . To lift a given payload into orbit, it is desirable to use a launch vehicle of minumum weight. The design of a...

Launch Vehicle Requirements

For the lunar landing mission, the Saturn V launch vehicle is required to inject an Apollo spacecraft payload of 90, 000 pounds into a 72 hour translunar trajectory. To accomplish this, this launch vehicle first injects the payload into a 100-nautical mile earth parking orbit by means of successive burns and separation of the S-IC stage, S-II stage and a first burn of the S-IVB stage. After a final checkout of the Apollo spacecraft, the S-IVB stage engine is re-ignited at the proper position in...

Saturn V Apollo Mission Objectives

The ultimate objective of the Saturn V - Apollo program is manned lunar landing within the present decade. Fifteen space vehicles are planned for attaining this objective. In the first two Saturn V - Apollo flights, SA-501 and SA-502, the mission objectives are flight testing the launch vehicle and testing of the CM heat shield under lunar re-entry velocity conditions. The objective of SA-503, through SA-506 flights is qualification or man-rating of the space vehicle. The seventh Saturn V -...

Engine Gimballing System

The Saturn V engine gimballing system positions the gimballed engines of the active stage to provide the thrust vectors required for vehicle control. In performing this function, the gimballing system is controlled by commands initiated by the attitude control and stabilization function. Refer to Paragraph 20-35. The engine gimballing system steers the vehicle along its trajectory by providing engine thrust vectors for pitch, yaw, and roll control except for the S-IVB stage . The system is...

What Is A Saturn

A brief description of the engine components follows. Table 22- 4 lists the engine performance parameters and mechanical characteristics. A schematic diagram of the engine is illustrated in Figure 22- 11. 22-35. Thrust Chamber. The thrust-chamber body consists of a cylindrical section, a narrowing throat section and an expansion section. The body is constructed of longitudinal brazed stainless steel tubes. An intake manifold routes fuel through the tubing, cooling the thrust chamber and...

Implementation

Radio frequency equipment carried aboard the Saturn IB instrument unit is integrated with earth-based equipment to provide the position and velocity data for mission control and post-flight evaluation of the mission. The radio frequency tracking sys tems include All of these systems except AROD are operational for the Saturn IB program. The AROD system is a developmental system. The systems are described below. 13-13. AZUSA. This system is the same as used for Saturn I. Refer to Paragraph 6-52....

Rca Computer

The RCA-110 Computer is a general-purpose digital computer capable of automatic monitoring and control. This computer is comprised of five major sections. The major sections of the computer are control, input, output, storage and arithmetic. The computer data are presented in Table 20-1. 20-6. Input Output Section. Information is transferred into, and out of, the computer by means of input output devices. Data to be processed, or programs to be performed, are read into the machine by paper...
