As shown in Figure 2, all of these data were fed back to the plotting rooms on a finely tuned schedule controlled by a system of time interval bells that rang throughout each harbor defense system.. To obtain accurate data of the target's position and relative motion, Pollen developed a plotting unit (or plotter) to capture this data. It was developed by Hannibal Ford of the Ford Instrument Company. The computer solved the torpedo triangle and calculated the gyro angle and the torpedo spread angle. Like the plotter, the primitive gyroscope of the time required substantial development to provide continuous and reliable guidance. Even with as much mechanization of the process, it still required a large human element; the Transmitting Station (the room that housed the Dreyer table) for HMS Hood's main guns housed 27 crew. This new bomb computer was revolutionary in that the release command for the bomb was given by the computer, not the pilot; the pilot designated the target using the radar or other targeting system, then "consented" to release the weapon, and the computer then did so at a calculated "release point" some seconds later. Along with qualitative information, this report include the quantitative analysis of various segments in terms of market share, growth, opportunity analysis, market value, etc. Fire control computer listed as FC CPTR Looking for abbreviations of FC CPTR? By the 1950s gun turrets were increasingly unmanned, with gun laying controlled remotely from the ship's control centre using inputs from radar and other sources. The system in the B-29 employed analog electromechanical computers … FCC - Fire-Control Computer. It was located in the conning tower on the starboard side between the helmsman’s station and the attack periscope. They are typically installed on ships, submarines, aircraft, tanks and even on some small arms—for example, the grenade launcher developed for use on the Fabrique Nationale F2000 bullpup assault rifle. Deploy a VICTORY-compliant ground vehicle computer that’s designed and tested for nuclear survivability; Get the Ultimate Fire Control Solution. A large part of this preeminence can be attributed to the work of Hannibal Ford and William New-ell. The key advantage is that the weapon can be released accurately even when the plane is maneuvering. Using the range finders, the director was able to produce a continuously varying set of outputs, referred to as line-of-sight (LOS) data, that were electrically relayed to the Mark 1 via synchro motors. The main difference between these systems and the ones on ships was size and speed. Essentially an electromechanical analog computer, the Mark 1 was electrically linked to the gun mounts and the Mark 37 gun director, the latter mounted as high on the superstructure as possible to afford maximum visual and radar range. The early versions of the High Angle Control System, or HACS, of Britain's Royal Navy were examples of a system that predicted based upon the assumption that target speed, direction, and altitude would remain constant during the prediction cycle, which consisted of the time to fuze the shell and the time of flight of the shell to the target. FC CPTR - Fire control computer. Combined with the long range of the guns, this meant that the ships moved a considerable distance, several ship lengths, between the time the shells were fired and landed. Opinions differed on which was the best point in the ship's roll to fire, but most gunners tried to fire at the beginning or end of the roll, when the ship was momentarily stationary. Once the firing solution is calculated, many modern fire-control systems are also able to aim and fire the weapon(s). NoxPlayers provides keyboard control for the player in order to take action as fast as possible. Kirishima was set aflame, suffered a number of explosions, and was scuttled by her crew.  The effectiveness of this combination was demonstrated in November 1942 at the Third Battle of Savo Island when the USS Washington engaged the Japanese battleship Kirishima at a range of 8,400 yards (7.7 km) at night. 4.0. Even if the system is unable to aim the weapon itself, for example the fixed cannon on an aircraft, it is able to give the operator cues on how to aim. It is considered a masterpiece of mechanical computing design. The last combat action for the analog rangekeepers, at least for the US Navy, was in the 1991 Persian Gulf War when the rangekeepers on the Iowa-class battleships directed their last rounds in combat. The Mark 1, and later the Mark 1A, Fire Control Computer was a component of the Mark 37 Gun Fire Control System deployed by the United States Navy during World War II and up to 1969 or later. Firestick Remote Control allows you to control your fire TV directly from iPhone/iPad using intuitive swipe based touch controls. to perform other actions simultaneously, such as tracking the target or flying the aircraft.

Digital fire control computers were not introduced until the age of minicomputers in the mid 1970s. Although listed in Land based fire control section anti-aircraft fire control systems can also be found on naval and aircraft systems. New York City, NY: June 30, 2020 – Published via (Wired Release) –Recent Research and Future Market Potential of Mortar Fire Control Computer Market in Global Industry. Both are complete with navigation system, self-laying capability and fire control computer. Use Keyboard Control to shot. They can be used to aim machine guns, small cannons, guided missiles, rifles, grenades, rockets—any kind of weapon that can have its launch or firing parameters varied. These devices used a gyroscope to measure turn rates, and moved the gunsight's aim-point to take this into account, with the aim point presented through a reflector sight. Gun directors were topmost, and the ends of their optical rangefinders protruded from their sides, giving them a distinctive appearance. But the B-29 was the first production aircraft to use them to remotely aim and fire aircraft gun turrets. In addition, as the fire control computer became integrated with ordnance systems, the computer can take the flight characteristics of the weapon to be launched into account.  Although the trials in 1905 and 1906 were unsuccessful, they showed promise. CCFM (Consolidated Compartment Fire Model version VENTS) is a two-layer zone-type compartment fire model computer code. The basic fire control principles of gun against a surface target are then applied to the control of Antiaircraft guns, Antisubmarine Weapons, Torpedoes, Rockets and Guided Missiles. Night naval engagements at long range became feasible when radar data could be input to the rangekeeper. She had been hit by at least nine 16-inch (410 mm) rounds out of 75 fired (12% hit rate). The Fire Control Computer is a block that allows for control of all weapons on the vehicle from anywhere within the range of the computer. The use of director-controlled firing, together with the fire control computer, removed the control of the gun laying from the individual turrets to a central position; although individual gun mounts and multi-gun turrets would retain a local control option for use when battle damage limited director information transfer (these would be simpler versions called "turret tables" in the Royal Navy). The report on Global Mortar Fire Control Computer Market offers in-depth analysis on market trends, drivers, restraints, opportunities etc. The pipper shows the pilot where the target must be relative to the aircraft in order to hit it. Fire control equipment installed in the gun houses includes devices which elevate and train the guns automatically in response to gun orders from the computer, as well as instruments and controls which allow the gun crews to check the automatic settings and to position the guns manually in the event of failure of the automatic positioning equipment. will affect its trajectory, so having accurate information is essential for a good solution. The need to spot artillery shells was one of the compelling reasons behind the development of naval aviation and early aircraft were used to spot the naval gunfire points of impact. The main part of the fire control system was the electro-mechanical torpedo data computer (Torpedo-Vorhaltrechner) or TDC designed and manufactured by the Siemens Company. It was difficult to put much weight of armour so high up on the ship, and even if the armour did stop a shot, the impact alone would likely knock the instruments out of alignment. Given these inputs, the Mark 1 automatically computed the lead angles to the future position of the target at the end of the projectile's time of flight, adding in corrections for gravity, relative wind, the magnus effect of the spinning projectile, and parallax, the latter compensation necessary because the guns themselves were widely displaced along the length of the ship. The LOS data provided the target's present range, bearing, and in the case of aerial targets, altitude.  These devices were early forms of rangekeepers. The pilot will then wait until the probability reading is satisfactorily high before launching the weapon. Alternatively, an optical sight can be provided that an operator can simply point at the target, which is easier than having someone input the range using other methods and gives the target less warning that it is being tracked. Typically, the cannon points straight ahead and the pilot must maneuver the aircraft so that it oriented correctly before firing. The original fire-control systems were developed for ships. The reasons were for this slow deployment are complex.  It is a major advantage for a warship to be able to maneuver while engaging a target. Sometimes, for very long-range rockets, environmental data has to be obtained at high altitudes or in between the launching point and the target. Meanwhile, a group led by Dreyer designed a similar system. Torpedo Data Computer Mark 3, Mark 3, Mods 5 to 12 inclusive, O.P. It was also deliberately designed to be small and light, in order to allow it to be easily moved along with the guns it served. To this he added a gyroscope to allow for the yaw of the firing ship. Read more. If the rounds missed, an observer could work out how far they missed by and in which direction, and this information could be fed back into the computer along with any changes in the rest of the information and another shot attempted. The Mark 1, and later the Mark 1A, Fire Control Computer was a component of the Mark 37 Gun Fire Control System deployed by the United States Navy during World War II and up to 1969 or later. The radar-based M-9/SCR-584 Anti-Aircraft System was used to direct air defense artillery since 1943. Earlier screw-powered capital ships were capable of perhaps 16 knots, but the first large turbine ships were capable of over 20 knots. Once the pilot maneuvers the aircraft so that the target and pipper are superimposed, he or she fires the weapon, or on some aircraft the weapon will fire automatically at this point, in order to overcome the delay of the pilot. 4. The Japanese during World War II did not develop radar or automated fire control to the level of the US Navy and were at a significant disadvantage..

It was developed by Hannibal Ford of the Ford Instrument Company . Moreover, in naval engagements it is also necessary to control the firing of several guns at once. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increased the range of the guns that the main problem became aiming them while the ship was moving on the waves. However, the anti-aircraft value of analog computers such as the Mark 1 was greatly reduced with the introduction of jet aircraft, where the relative motion of the target became such that the computer's mechanism could not react quickly enough to produce accurate results. The FCC, BBC and FAB MRTUs are turned on with the switch labeled FCC/MUX ON (fig 4-14). Additional inputs to the Mark 1 were continuously generated from the stable element, a gyroscopic device that reacted to the roll and pitch of the ship, the pitometer log, which measured the ship's speed through the water, and an anemometer, which provided wind speed and direction. Data from these stations were then passed to plotting rooms, where analog mechanical devices, such as the plotting board, were used to estimate targets' positions and derive firing data for batteries of coastal guns assigned to interdict them. Small guns with limited range used simple telescopic sights. The legacy electro-mechanical fire-control calculator was replaced by a digital fire-control computer, greatly increasing the system's effectiveness. Fire-control systems are often interfaced with sensors (such as sonar, radar, infra-red search and track, laser range-finders, anemometers, wind vanes, thermometers, barometers, etc.) Modern fire-control computers, like all high-performance computers, are digital. Land based fire control systems can be used to aid in both Direct fire and Indirect fire weapon engagement. These sorts of effects are noticeable for any sort of gun, and fire-control computers have started appearing on smaller and smaller platforms. Rangefinder telescopes on a separate mounting measured the distance to the target. 5. Keyboard feature to simplify text input and search. The wreck of Kirishima was discovered in 1992 and showed that the entire bow section of the ship was missing. Fire Control Fundamentals, NAVPERS 91900, 1953, was created to introduce sailors to the basics of weapons fire control. The FCC processes and computes data for all fire control capabilities on board the helicopter (fig 4-8). These guns were capable of such great range that the primary limitation was seeing the target, leading to the use of high masts on ships. Small radar units were added in the post-war period to automate even this input, but it was some time before they were fast enough to make the pilots completely happy with them. Visual range measurement (of both target and shell splashes) was difficult prior to availability of Radar. By the start of World War II, aircraft altitude performance had increased so much that anti-aircraft guns had similar predictive problems, and were increasingly equipped with fire-control computers. The incorporation of radar into the fire control system early in World War II provided ships the ability to conduct effective gunfire operations at long range in poor weather and at night. There the fire direction teams fed in the location, speed and direction of the ship and its target, as well as various adjustments for Coriolis effect, weather effects on the air, and other adjustments. This problem was solved with the introduction of the gyroscope, which corrected this motion and provided sub-degree accuracies. In a typical World War II British ship the fire control system connected the individual gun turrets to the director tower (where the sighting instruments were located) and the analogue computer in the heart of the ship. Once the system was "locked" on the target, it produced a continuous fire control solution. Lead angles and corrections were added to the LOS data to generate the line-of-fire (LOF) data. However, the credit has usually been withheld. Arthur Pollen and Frederic Charles Dreyer independently developed the first such systems. ble fire-control systems for aiming large naval guns and setting fuze times on the shells for destroying either surface or air targets. It involved firing a gun at the target, observing the projectile's point of impact (fall of shot), and correcting the aim based on where the shell was observed to land, which became more and more difficult as the range of the gun increased.
