The sealing characteristics of the Solid Rocket Booster O-rings are enhanced by timely application of motor pressure. a. Ideally, motor pressure should be applied to actuate the O-ring and seal the joint prior to significant opening of the tang-to-clevis gap ( to milliseconds after motor ignition). The Space Shuttle Challenger disaster was a fatal incident in the United States space program that occurred on Tuesday, Janu , when the Space Shuttle Challenger (OV) broke apart 73 seconds into its flight, killing all seven crew members aboard. The crew consisted of five NASA astronauts, one payload specialist, and a civilian ies: Rogers Commission. The Space Shuttle Solid Rocket Booster (Space Shuttle SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight and provided the majority of the Space Shuttle's thrust during the first two minutes of flight. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, Manufacturer: Thiokol, later ATK, United .   The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized burning gas from within the solid rocket motor to reach the .

He was the director of the Space Shuttle Solid Rocket Motor Project at the time of the Challenger accident and, later, vice president of engineering for space operations during the redesign and requalification of the solid rocket motors. James R. Hansen is professor of history and director of the Honors College at Auburn by: Solid rocket booster (SRB) is a large solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent Many launch vehicles, including the Ariane 5, Atlas V, and Space Shuttle, have used SRBs to give launch vehicles much of the thrust required to place the vehicle into Space Shuttle used two Space Shuttle SRBs, which were . The cause of the disaster was traced to an O-ring, a circular gasket that sealed the right rocket booster. This had failed due to the low temperature (31°F / °C) at launch time – a risk that several engineers noted, but that NASA management dismissed. NASA’s own pre-launch estimates were that there was a 1 in , chance of shuttle. "It is easier to blame a thing than to blame people" was the response of a Navy SEAL and son of one of the Apollo capsule design engineers when told about the joint rotation flaw in the Space Shuttle solid rocket motor (SRM). Indeed, it is easier to blame cold temperatures and a decision made at the last minute and under management pressure.

A faulty O-ring in the right Solid Rocket Booster led to the destruction of the Space Shuttle Challenger on Janu Adapted from material by the Department of Philosophy and Department of Mechanical Engineering Texas A&M University NSF Grant Number DIR Introduction to the Case. On Janu , seven astronauts were killed when the space shuttle they were piloting, the Challenger, exploded at just over a minute into the flight. The Space Shuttle solid rocket motor (SRM) con-sists of 11 separate weld-free steel segments (cylindri-cal shells) approximately 12 ft in diameter. Adjoin-ing case segments are mechanically assembled using tang-clevis joints, with each joint having steel pins around its circumference (fig. 1). An inves-File Size: 1MB. Silicon rubber sealing ring is widely used to encapsulate differ-ent components of the solid rocket motor (SRM). Its reliability plays an important role in the safety and service life of the solid rocket motor. Developed countries have devoted to extend the solid rocket motor service life and have gotten significant achievements.
