The medium weight test is a test performed on the medium weight shock machine. Weight of the test item including fixture to attach it to the test machine shall be less than a maximum of 7,400 pounds (3,400 kg). Heavyweight. The heavyweight test is a test performed on a standard or large floating shock platform.
Two straps, known as "hiking straps", run lengthwise along the floor from the bulkhead to the stern. These and a tiller extension allow a sailor to hang off the side for weight distribution—commonly called "hiking out". This can be crucial to keeping the boat more upright during heavy air, allowing greater speed through the water.
The powder magazine rooms are separated from the turret platforms by a pair of 1.5-inch STS annular bulkheads under the barbettes for flashback protection. [72] The installation of armor on the Iowa s also differed from those of earlier battleships in that the armor was installed while the ships were still "on the way" rather than after the ...
The bulkhead, left, prevents water from entering at Lock and Dam No. 2 so work can be done on the gates to the chamber, right, Jan. 30 on the Mississippi River in Hastings, Minnesota.
Mini-bulk carriers are prevalent in the category of small vessels with a capacity of under 10,000 DWT. Mini-bulk carriers carry from 500 to 2,500 tons, have a single hold, and are designed for river transport. They are often built to be able to pass under bridges and have small crews of three to eight people.
The S-II's common bulkhead design was tested in 1965 on the subscale Common Bulkhead Test Tank (CBTT), made of only 2 LH2 tank cylinders. [4] The LOX tank was an ellipsoidal container of 10 meters diameter and 6.7 meters high holding up to 83,000 US gallons (310 m 3) or 789,000 pounds (358 t) of oxidizer. [5]
The aft pressure bulkhead is the white circular component; its web-like structure led a NASA technician to attach a large model spider to it for comedic effect. The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [1]
The underwater protection was an internal "bulge" that consists of four longitudinal torpedo bulkheads forming a multi-layered system designed to absorb the energy from an underwater explosion equivalent to 700 pounds of TNT (1.3 GJ). The protection system was designed for the torpedo bulkheads to deform and absorb energy while several ...
