CAREFUL DIETS FOR MISSILES

Year Published: 1960s

Format: 16mm

Description: Flames shoot from a rocket thrust booster and workers add fuel to cylinders in the opening moments of "Careful Diets for Missiles" as a narrator dramatically proclaims, "Food — for the hungry bellies of rockets and missiles. Their diets are critical. The big jobs eat a lot and mixing it by hand isn't good enough anymore." With that, the logo for Toledo Scales appears onscreen (mark 01:20) and we’re transported to aerospace manufacturer Thiokol Chemical Corporation in Utah while being told how the two companies worked together to automate the process. Engineers work at control consoles in this early 1960s production while others tinker with circuitry "to do a big job with care and precision." Solid propellant are shown being mixed in vats and beginning at mark 02:48 we learn the three stages of creating solid propellant, beginning with mixing aluminum power and polymer into a pre-mix, then forming it into an oxidizer, and finally combining the mixture and oxidizer into a final mix. The film continues by detailing each step of the process with the narration illustrated by matching scenes. Come mark 06:56, it is explained how an epoxy also is added to the final mix and we learn about the four final mix operations — each one performed in separate buildings and all monitored from a remote location "by one man." A controller turns a key at mark 09:10 to unlock the master control console while also checking quality control sheets. The grayish product is seen at mark 12:05 while the narrator explains, "Solid propellant — a meticulous food for giant, monolithic space boosters ready to protect a nation or send vehicles hurdling into space to find the promise of tomorrow." Thiokol was an American corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. It was founded in 1929. Its initial business was a range of synthetic rubber and polymer sealants, and Thiokol was a major supplier of liquid polymer sealants during World War II. When scientists at the Jet Propulsion Laboratory discovered that Thiokol's polymers made ideal binders for solid rocket fuels, Thiokol moved into the new field, opening laboratories at Elkton, Maryland, and later production facilities at Elkton and at Redstone Arsenal in Huntsville, Alabama. Huntsville produced the XM33 Pollux, TX-18 Falcon, and TX-135 Nike-Zeus systems. It closed in 1996. In the mid-1950s the company bought extensive lands in Utah for its rocket test range, and in 1986 was found at fault for the destruction of the Space Shuttle Challenger and the deaths of its astronauts. Thiokol continues to have major operations in the state, at Magna and Promontory (manufacture of the Space Shuttle's solid rocket motors), and its current headquarters at Brigham City. As of 2005 the company employed over 15,000 people worldwide and records annual sales of around US$840 million.PeriscopeFilm 702K subscribers Videos About Support Us on Patreon

for food for the hungry bellies of rockets and missiles their diets are critical the big jobs eat a lot and mixing it by hand isn't good enough anymore it's slow risky pass a [Music] too scale and thol teamed up to build new kitchens automated batch mix facilities to prepare careful diets automatically on a Utah desert the most modern Concept in America took shape control consoles with graphic displays solid state circuitry button logic color coding interlocks and failsafe devices to do a big job with care and precision it's done with speed accuracy uniformity safety the food is ugly yet beautiful full of muscle the strength of a Nation it feeds multi-million pound thrust boosters it's called solid propellent solid propellant is made in three stages first aluminum powder and polymer binder are Blended to form a premix second various sized particles of ammonium perchlorate form an oxidizer third the oxidizer and premix are Blended at a Final Mix station where an epoxy curing agent is added each production stage is handled in a separate building first stage premix highly crucial because aluminum powder is the fuel in the final solid propellant the container carries 5,000 lb of aluminum powder mean cantankerous so hard to handle that only a specially designed feeder could harness it a premix container is positioned beneath the discharge point the rest of the operation is remotely controlled green lights mean go batch number formula number date time and required weight are loged polymer a binding agent is fed from storage tanks through heat traced pipes to maintain constant viscosity the premix container receiving the polymer rests on a special load cell platform programmed to measure only net weight all feedings in the entire system are on a two-speed basis P fast and dribble load cells signal the feeder a tolerance check for near Perfection then read out of weight and tank number from which it was drawn now an automatic advancement to aluminum which is also weighed into the premix can the small amount of powder in suspension is considered at final cutof the weight of aluminum is checked for accuracy against programmed top an if sufficiently accurate it is recorded aluminum and polymer are Blended thoroughly ceiling avoids contamination formula number and batch characteristics follow the premix container to the Final Mix building the second stage preparing the oxidizer in a remote building various particle sizes of ammonium perchlorate similar to granulated and powdered sugar are conveyed to bins above a way Hopper the entire operation is controlled and monitored remotely way Hopper and check scale are zeroed and the information is loged each material is weighed in turn on an analog to digital scale system fast then dribble and check for proper tolerance the materials are individually emptied into a transfer bin resting on a check scale where a final tolerance check is made there accumulated weight is logged and the oxidizer is ready for delivery to Final Mix the third and last production stage here oxidizer is combined with the premix and an epoxy curing agent is added because of the need for massive quantities of fuel there are four Final Mix operations each in a separate building all are controlled and monitored from a remote Master Control Center by one man the operations are controlled by preset formula boards variations can be made in weights ratios tolerances sequences and mix cycle for almost unlimited flexibility closed circuit television monitors each premix operation oxidizer in a sealed container is placed on a specially designed elevator and tilting fixture and positioned onto a feeder weights of the container feeder and tilt mechanism are subtracted leaving only the weight of the oxidizer available to to the control panel epoxy is pressure fed to a scale Hopper volumetrically then weighed into the mixer on a loss in weight principle finally the premix load cells check its weight against the data on the card it also discharges on loss of weight method temperatures are maintained by controlled heat in a water [Applause] jacket all ingredients are in [Music] place and the building is cleared a safety warning signal is set the final mixing operation cannot begin until a Personnel key unlocks the master control console quality control sheets from the oxidizer and premix batches are used in preparing the Final Mix log sheet before the operation can begin all components must be within tolerance when all stations are go the operator touches the start button batch and formula numbers date time and other quality control information is logged the oxidizer weight is sensed the scale is zeroed and flow begins the oxidizer is dynamically screened to prohibit contamination then delivered into the mixer the system makes a tolerance check and the weight is logged as the premix begins to flow mixing begins [Music] automatically again again a tolerance check and a log entry after a preset mixing time blending stops and epoxy is carefully added in a precise [Music] amount more mixing until the batch has reached the correct homogenous mass at any time the system can be switched to manual control should a nogo situation occur because of malfunction or out of Tolerance condition the quality control operator will decide to reject the batch or bring it within manufacturing limits the safety key over rides the automatic program this batch is recorded in red the manufacturer receives a complete log of all materials accurate to within one part in 10,000 on loads up to 3,000 lb a careful diet in 2 and 1/2 hours a little more than half the time formerly [Music] required solid propellant a meticulous food for giant monolithic space boosters ready to protect the nation or send Vehicles hurtling into space to find the promise of tomorrow [Music]
