Clamp Loads and Bending Stresses in Aircraft Tubing Installations
This SAE Aerospace Information Report (AIR) contains information relative to stresses and loads developed in tubes caused by tube deflections encountered in misaligned installations.
Users are advised that when calculating the stresses and loads of a tubing system, the yield strength of existing loop clamp material is significantly lower than the tubing materials specified herein and should be considered.
Scope has been revised. ARP994 added to Sections 2 and 3. Section 5 added. Figure 1 redrawn and re-identified as Tables 1, 2, and 3. Loop clamps in Figure 1 revised to show mounting position is above tube centerline. Wall thickness for titanium sizes Ø 1.250 and Ø 1.500 in Table 3 revised to coincide with AS5620 specifications, resulting in new P values.
