Resolved Question: Wireless power electricity induction?
Hi,

I want to power a 3 mm typical (common) infrared LED via wireless electric transfer using NORMAL INDUCTION (NOT RESONANCE).

- If I use approximately 1.5 cm diameter coil with at least 15 windings for both transmitter and receiver, how far can the two coils be before the light dims to only 70% of the maximum LED light luminosity (i just want to get an idea of the max range of induction energy transfer - seems hard to find on internet.)

- can i get smaller diameter and lesser windings for above case if the distance i want is less than 12 cm??

- resonance induction –> it’s a patented technology is it??

- will such magnetic field interfere with devices such as mobile phone’s circuitry??

- is it perfectly safe for people if the coils are sealed??

Thanks for any suggestions and information

Tumblr Fairchild AC-119 Shadow/Stinger
The Fairchild AC-119G Shadow and AC-119K Stinger were developed during the Vietnam War. They replaced the inadequate AC-47 Spooky and supplemented the newer AC-130. The AC-119 program (Project Gunship III) came after the AC-130, not before.
Design and development
By late 1967, the idea of the fixed-wing gunship had been proven so successful that the United States Air Force was having a difficult time keeping up with demand. The newer AC-130s that had been created under Project Gunship II were effective, but were being mostly used for interdiction of the Ho Chi Minh Trail. Furthermore, the C-130 airframe was in active service as a transport, vital to the war effort in South East Asia. The Air Force desperately needed a new gunship to replace the vulnerable and underpowered AC-47 in supporting “Troops In Contact” (known as TIC), as well as, supplementing the AC-130 in attacking targets on the Ho Chi Minh Trail.
The C-119 Flying Boxcar presented an obvious choice, having been phased out of frontline service in favor of the C-123 and C-130, and with the stock of available airframes in U.S. Air Force Reserve being sufficient. In February 1968, under the USAF program Project Gunship III, 26 C-119Gs were converted to AC-119G standard, initially taking on the name “Creep,” but later assigned the callsign “Shadow.”[1] These aircraft were primarily intended to replace the AC-47 in the TIC role. In addition, Fairchild-Hiller, which was contracted for all the conversions, converted 26 C-119Ks into AC-119Ks primarily for the “truck hunter” role over the Ho Chi Minh Trail. These aircraft were called “Stingers” primarily in reference to the two M61 Vulcan 20 mm cannons they carried in addition to the AC-119G’s four GAU-2/A miniguns.
Project Gunship III, being a follow on to the success of the AC-130 series, meant that the AC-119 was a far more advanced aircraft in both its iterations than the AC-47. Even the TIC AC-119G featured some of the most up-to-date ECM and radar equipment, as well as more basic technology including an AVQ-8 Xenon light, a Night Observation Sight (NOS) and an LAU-74/A flare launcher.
The AC-119K, designed to hit trucks on the Ho Chi Minh Trail, was significantly more advanced. Included in the conversion was the AN/APN-147 Doppler Navigation radar, AN/AAD-4 Forward Looking Infrared (FLIR), AN/APQ-133 side-looking beacon tracking radar and AN/APQ-136 search radar.
The armament scheme for both aircraft was significantly simpler than that of the AC-130. The AC-119G had a total of four GAU-2A/A miniguns in SUU-11A/A pods, all on mounts similar to those used on early AC-47s. Like late model AC-47s, these were soon changed to the purpose-built MXU-470/A minigun modules. The AC-119K, needing a more powerful and longer range “punch” to take out vehicles, featured two M61 20 mm cannons in addition to the four Miniguns of the AC-119G

Lockheed AC-130A/H Spectre/AC-130U Spooky AC-130A Spectre
The A-model gunship was the first AC-130 model. The aircraft is 97 feet 9 inches long and 38 feet 3 inches tall. It has a wingspan of 132 feet 7 inches and a wing area of 1,745 sq. feet. Initially, the C-130 had a maximum speed of 384 mph and an unrefueled range of 2,450 miles with maximum load. However, with the aerial refueling modification, the range for the later model gunships was only limited by crew endurance.
The high-wing design of this aircraft and its large capacity made it especially suited as a gunship. The first gunship, the AC-47, with low wings, reduced its field of fire. Having the guns below the wings eliminated the basic problem of the AC-47. Also, the large C-130 could carry more ammunition for its heavier weapons. The AC-47 was equipped with three 7.62mm miniguns. In contrast the AC-130A carried 7.62mm and 20mm weapons; the AC-130H fired 20mm, 40mm and 105mm guns; and the newest gunship, the AC-130U, is equipped with 25mm, 40mm and 105mm weapons.
The C-130 gunship was a new weapon system in an old airframe. Therefore, there were a number of firsts that one model or another chalked up for the gunship. Spectre was operationally tested at Eglin Air Force Base, Fla., from June to September 1967. It initially deployed to Nha Trang, Republic of Vietnam Sept. 20, 1967, and flew its first combat mission Sept. 27. Its first truck busting mission was flown Nov. 8, 1967, and all A-model gunships were assigned to Detachment 2, 14th Commando Wing. In 1968, Det. 2 was assigned to the 8th Tactical Fighter Wing and became the 16th Special Operations Squadron. At that time the C-130A was renamed the AC-130A.
AC-130H Spectre
The Vietnam-era AC-130E “Pave Spectre” was an improved version of the AC-130A “PAVE PRONTO” aircraft. The C-130E was equipped with more powerful versions of the Allison T56 turboprop engines. The AC-130E was later upgraded to AC-130H standards under project “Pave Spectre II”
The AC-130 is an excellent fire support platform with outstanding capabilities. With its extremely accurate fire control system, the AC-130 can place 105mm, 40mm and 25mm munitions on target with first round accuracy. The crew of these aircraft are extremely proficient working in military operations in urban terrain [MOUT] environments. Many ground units have begun to use Infra-red (IR) tape either as arm bands or sewn to the top of their ballistic helmet for marking troops and vehicles, especially when working with the AC-130. It only takes a very small piece of IR tape to be distinguished as friend or foe by an AC-130, and anything larger than a one inch by one inch piece is going to white out a large portion of the monitor aboard the aircraft.
AC-130U Spooky
Continuing the distinguished combat history of side-firing AC-130 gunships, the new AC-130U Spectre gunship was fielded as a replacement for the AC-130A aircraft and to supplement the AC-130H gunship fleet. Its mission is to support conventional and joint special operations forces any time, any place. The AC-130U Gunship program initially consisted of 13 [later 17] new Lockheed C-130H airframes, modified by Boeing, which assumed responsibility for the AC-130U contract when it merged with the Rockwell Corporation, the original contractor on the program. The modifications allow the aircraft to perform the full range of special operations and conventional gunships missions. It provides surgical firepower, night and adverse weather operations, and extended loiter time on target in Special Operations Forces (SOF) and conventional roles. The AC-130U is named for the AC-47D and has the “Spooky” nickname rather than the “Spectre” nickname used by all other AC-130 gunships.
The AC-130U was armed with a 25mm Gatling-gun (capable of firing 1800 rounds per minute), a single-barrel, rapid-fire 40mm Bofors cannon, and a 105mm Howitzer. The AC-130U replaced the two 20mm cannon used on the AC-130H with one trainable 25mm cannon while retaining the other weapons. The AC-130U employs the latest technologies and can attack two targets simultaneously.
The U-model gunship is one of the most complex aircraft weapon systems in the world today, containing more than 609,000 lines of software in its mission computers and avionics systems. Although it still uses the venerable Lockheed C-130 airframe, the AC-130U incorporates the latest sensor technology, along with an entirely new fire-control system, to substantially increase the gunship’s combat effectiveness. The fire control system offers a dual-target attack capability, whereby two targets up to one kilometer apart can be simultaneously engaged by two different sensors, using two different guns. All light-level television, infrared sensors, and the Hughes APQ-180 radar (also found on the F-15E Strike Eagle) provide night and adverse weather capability. The strike radar provides the first gunship capability for all weather/night target acquisition and strike.
The AC-130U is an excellent platform for working at night. The pilots are proficient with NVGs and the AC-130 carries various systems for working in the dark including FLIR, and LLTV. It has an LST and two laser designators, although these systems cannot be cued to each other. The APQ-180 fire control radar gives the AC-130 an adverse weather capability. They orbit at approximately 5,000-10,000? AGL around a target area in a 5 nm arc. AC-130U strengths include an excellent loiter time of up to 4 ½ hours. It is a superior platform for Troops in Contact (TIC), and is best used at night to optimize all of its sensors. It also has a superior communications suite. AC-130U weaknesses include decreased maneuverability and survivability in a high tech surface-to-air threat environment. It is a large target with slow speed and should not be used in a high threat environment in daylight. It also has a wide orbit pattern.
All weapons can be slaved to sensors which permit night or adverse weather operations. The AC-130U is a highly integrated weapons system. Within the AC-130U resides the Battle Management Center (BMC) where crew coordination is critical to the success of their missions. This BMC consists of five crew stations which are the Navigator (Nav), Fire Control Officer (FCO), Electronic Warfare Officer (EWO) and two Sensor Operators who control the Infrared Detection Set (IDS) and the All Light Level Television (ALLTV) systems.
To enhance survivability, emphasis has been placed on increasing the stand-off range of the gunship’s weapons system and improving first-shot accuracy. In addition, a set of electronic countermeasures has been installed to help defend the AC-130U against modern threats. The AC-130U gunship airframe is integrated with an armor protection system (APS).
