Structural behavior of the space shuttle SRM Tang-Clevis joint The space shuttle Challenger accident investigation focused on the failure of a tang-clevis joint on the right solid rocket motor. The existence of relative motion between the inner arm of the clevis and the O-ring sealing surface on the tang has been identified as a potential contributor to this failure.

The Space Shuttle Challenger accident investigation focused on the failure of a tang-clevis joint on the right solid rocket motor (SRM).

The existence of relative motion between the inner arm of the clevis and the O-ring sealing surface on the tang has been identified as a potential contributor to this failure. Finite element structural analyses have been performed to predict both deflections.

Structural Behavior of the Space Shuttle SRM Tang-Clevis Joint: NASA Technical Memorandum by Greene, Knight and Stockwell is the result of an in-depth and complex study of the SRM tang-clevis joint.

Due to Challenger space shuttle accident insignificant research has been done concerning structural behavior of field joints in solid rocket boosters (SRB).

The structural deformations between the clevis inner leg and the tang (male-to-female parts of joint), the sealing of the O-ring to prevent the hot gas in joints, has been neglected. 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, refurbished, and. Get this from a library. Structural behavior of the space shuttle SRM tang-clevis joint.

Results of a structural design study of an in-line bolted joint concept which can be used to assemble Space Shuttle Solid Rocket Motor (SRM) case segments are. The SRM case-to nozzle joint, which experienced several instances of O-ring erosion in flight, has been redesigned to satisfy the same requirements imposed upon the case field joint.

Similar to the field joint, cast-to-nozzle joint modifications have been made in the metal parts, internal insulation and O-rings. The structural design of a bolted joint with a static face seal which can be used to join Space Shuttle Solid Rocket Motor (SRM) case segments is given.

Results from numerous finite element parametric studies indicate that the bolted joint meets the design requirement of preventing joint opening at the O-ring locations during SRM pressurization.

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.

Hoversten, Paul. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA Prior to Challenger's launch, NASA was stretched to the limit. It had advertised the shuttle was providing cheap access to space, but this could only be achieved if the flight rate reached 20 per year, or one every two weeks.

But the shuttle turned out to be a maintenance nightmare. The Commission questioned personnel from Marshall Space Flight Center, the NASA center responsible for the shuttle's entire propulsion system, which included the Orbiter's Main Engine, the External Tank, and the SRB, and Morton Thiokol, the contractor responsible for the SRM (see appendix B, figs.

B–B). It began to uncover the true. This book is as detailed as you would expect from an engineer whose care and rigour at his job is obvious. You are plunged right into the heart of the daily grapple with issues of the re-usable hardware in the solid rocket boosters (blowby, erosion, putty, tang clevis field joint and of course dreaded temperature issues).Reviews: Almost all of the confidence in the structural support boot ring arises from the DM-8 test, which was less demanding than the DM-9 test, and from the experience with the design flown in previous Shuttle flights, from which the con- cept of the structural support outer boot ring has evolved.

SPACE TRANSPORTATION SYSTEM. SPACE SHUTTLE PROGRAM. The Space Shuttle is developed by the National Aeronautics and Space Administration. NASA coordinates and manages the Space Transportation System (NASA's name for the overall Shuttle program), including intergovernmental agency requirements and international and joint projects.

NASA also oversees the launch and space. The concept of a joint that rotates closed or does not rotate at all might be implemented for the case joint either with bolted flanges, as suggested by the group at NASA/Langley Research Center, or with a pinned tang-c~evis joint.

With the pin concept, the tang-clevis joint would have to be drawn into a smaller radius than the case cylinder. This book is an incredibly detailed exploration of history of the development of the Space Transportation System (aka space shuttle).

The book begins with a history of some pioneering work by Germans in WWII and follows the history of the development of the concept of the shuttle, how contracts were awarded to aerospace firms, and how the actual shuttle was s: 2.

Criticism of the Space Shuttle program stemmed from claims that NASA's Shuttle program failed to achieve its promised cost and utility goals, as well as design, cost, management, and safety issues.

Fundamentally, it failed in the goal of reducing the cost of space access. Space Shuttle incremental per-pound launch costs ultimately turned out to be considerably higher than those of expendable. NASA's Space Shuttle Program is designed to achieve this goal in the 's with a reusable space orbiter and a reusable booster.

This paper identifies the structural problems inherent in these craft and discusses the structural details of the orbiter design being studied by North American Rockwell's Space.

Thermal protection system (TPS) materials play an important role in the aerospace industry because they are used to manufacture the heat shield, i.e., the part that protects the structure, aerodynamic surfaces, payload of probes, missiles, war heads, and space vehicles from severe heating during entry flight through a planetary protective heat shield of the vehicle has to.

The SRM field-joint metal parts, internal case insulation and seals were redesigned and a weather protection system was added. In the STS L design, the application of actuating pressure to the upstream face of the O-ring was essential for proper joint sealing performance because large sealing gaps were created by pressure-induced deflections.

This book tells the story of the Space Shuttle in its many different roles as orbital launch platform, orbital workshop, and science and technology laboratory. It focuses on the technology designed and developed to support the missions of the Space Shuttle program. Each mission is examined, from.

You are plunged right into the heart of the daily grapple with issues of the re-usable hardware in the solid rocket boosters (blowby, erosion, putty, tang clevis field joint and of course dreaded temperature issues).Reviews: • SRM clevis joint was originally proportioned to INCREASE O-ring squeeze with rising pressure.

• After case fab was well under way, NASA initiated weight reduction to increase payload by reducing SRMcase cylinder thickness between clevis joints. This changed clevis joint behavior, DECREASING O-ring squeeze with rising pressure.In Linking the Space Shuttle and Space Stations, the author delves into the rich history of the Space Shuttle and its connection to these early space stations, culminating in the nine missions to dock the shuttle toMir.
