Variable Speed Fire Pump Controllers were invented and released with a UL Listing for fire pump service in 2003 by Master Control Systems, Inc. [1] [2] Paragraph 10.5.5 in the 2003 edition of NFPA-20 recognized Variable Speed as an accepted method for operating the fire pump. Then in the NFPA-20 2007 edition, section 10.10 was added to clarify ...
Like many other pieces of Coast Artillery fire control equipment, the deflection board was a mechanical analog computer that used methods of similar triangles to solve the problems of correcting fire for wind speed and direction, drift of the projectile, and angular travel of the target during the observing interval.

A German anti-aircraft 88 mm Flak gun with its fire-control computer from World War II. Displayed in the Canadian War Museum.. A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director and radar, which is designed to assist a ranged weapon system to target, track, and hit a target.
Memory cycle time was reduced to 2 microseconds. The version for the military was called the UNIVAC 1219 (known as the "Mk 152 Fire Control Computer.") [3] [4] It was part of the Navy's Mk 76 missile fire control system, used to control the AN/SPG-55 radar system.
The AN/SPG-53 was a United States Navy gun fire-control radar used in conjunction with the Mark 68 gun fire-control system. It was used with the 5"/54 caliber Mark 42 gun system aboard Belknap -class cruisers, Mitscher -class destroyers, Forrest Sherman -class destroyers, Farragut -class destroyers, Charles F. Adams -class destroyers, Knox ...
The fire remained 0% contained at 11 p.m. Tuesday as "extreme fire behavior" continued to challenge firefighters, according to the L.A. County Fire Department. Wind gusts up to 60 mph were ...
The equations implemented in the angle solver can be found in the Torpedo Data Computer manual. [40] The Submarine Torpedo Fire Control Manual [41] discusses the calculations in a general sense and a greatly abbreviated form of that discussion is presented here. The general torpedo fire control problem is illustrated in Figure 2.
