The structure of the aircraft serves as a ground except for circuits in the vicinity of the magnetic compass, in which the ground is away from the compass. Electrical panels for the distribution and control of power to the various electrical circuits are as follows:. Landing lights — two landing lights are provided as an integral part of each wing and are controlled by two switches located on the left electrical control panel.
Each light may be operated independently. Tagged as: ElectricalManualsystems. You must log in to post a comment. We respect your email privacy. DC-3 Operations Manual — Electrical. Each battery is mounted on a carriage located within a box below the fuselage floor.
Access is through two drop down panels on the outside of the nose section of the fuselage. Ground power — an external power plug is installed in the bottom of the fuselage forward of the wing leading edge. An amber light installed in the center of the overhead switch panel in the cockpit indicates when power is being furnished to the external power plug irrespective of battery switch position.
The battery switch should be placed in the external power position when power is plugged in. Battery switch — A single 3 position switch is installed on the right overhead switch panel in the cockpit to select aircraft batteries or ground power, with a center position for OFF. Generators 1. A P-1 generator rated for amps is installed on each engine. The system operates as one individual unit. Both generators through the controls and batteries are connected in parallel to one bus bar.
One generator with the batteries will provide ample power for operation of all required equipment. Reverse current relay — the reverse current relay is an automatic switching device. This unit connects the generator to the bus when generator output is normal and will disconnect the generator from the bus when there is a reverse current flow from the bus to the generator. The relay is operative only when the generator switch is on. Circuit breakers — each generator is protected by a amp circuit breaker located on the circuit breaker panel in the companionway.

Variable Frequency Drives. Power Inverters. Voltage Converters. Soft Starters. Few days ago, GoHz made a 24V W power inverter in home, sharing some design schematics and circuit diagrams.
Power inverter testing. The picture was taken in short-circuited.
Output waveform. The SPWM accuracy of EG was not high enough waveform, so the inverter output was not good enough as pure sine wave. The dead zone time was a bit long 1uSwhere the zero-crossing point did not look good, in order to ensure the safety of the tube, GoHz did not adjust it.
This was a full load test on the power inverter, two water heaters, about watt, the water was boiling completely.
Maximum connected load was watt for approx 10 seconds, due to the DC power supply limitation paralleling a large DC battery and two small batteriesGoHz did not continue test it. Adjust the inverter power limitation potentiometer, limit the maximum power at watt, a little greater than wattthe power inverter works for less than two seconds before it turn off the output. Short circuit protection is also set about two seconds to turn off the output. Due to the EG programming reason, the power inverter will continuous work after a few seconds if the power supply is not cut off.
This power inverter has a good starting ability, it only takes about 1 second for two parallel watt solar lamps. This inverter is designed to power about watt, the headline of this paper is watt is because the DC power supply maximum output current is A, so GoHz tested it at watt, for more than 12 hours testing, it can work well at wattthere would be no problem for the actual load at watt.
This is the foreline tube D level waveform when the power inverter was in w full load. Expanding the foreline tube D level waveform when the inverter in w full load. This is the power inverter in no-load power consumption test. It can be seen from two multimeter, no-load power consumption is Forward toroidal transformer. Using 4 pairs ixfh80n10, 80A, V, Backward power tube is 4 set FQA28N50, output inductor is sendust 52mm with 1.
Short circuit test. This power inverter is sensitive in short circuit protection, after more than times short circuit tests power on short circuit, no-load short circuit, full load short circuit, loading short circuitthe power inverter is still work good. The output terminals of the inverter and the tweezers were scarred. Here is the circuit section, get understanding the basics of this power inverter, DIY an inverter now. Forward board DC-DC power circuit board, conventional push-pull.
It has undervoltage, overvoltage, overcurrent protection, overcurrent protection is implemented by test tube drop. Download PDF file Backward DC-AC schematic, using conventional circuit too, there is nothing new places, the unique is the additional high-voltage detection circuit, means when the DC voltage is higher than V DC, the auxiliary power is turned on, and the backward circuit is beginning to work.Assortment of aircraft wiring diagram software you can download at no cost.

Many people can understand and understand schematics called label or line diagrams. This type of diagram is like going for a photograph from the parts and wires all connected up.
A wiring diagram is a schematic which uses abstract pictorial symbols to show each of the interconnections of components in a system. Wiring diagrams comprise certain things: symbols that represent the constituents within the circuit, and lines that represent the connections with shod and non-shod. Therefore, from wiring diagrams, you realize the relative location of the ingredients and how these are connected. Wiring diagrams mainly shows the physical position of components and connections in the built circuit, and not necessarily in logic order.
It emphasizes on the layout of the wires. Schematics emphasize on how circuits work logically. To read a wiring diagram, first you have to find out what fundamental elements are included inside a wiring diagram, and which pictorial symbols are used to represent them.
The common elements in a very wiring diagram are ground, power, wire and connection, output devices, switches, resistors, logic gate, lights, etc.
A line represents a wire. Wires are widely-used to connect the constituents together. All points down the wire are the same and connected. A black dot is utilized to suggest the injunction of two lines. Main lines are represented by L1, L2, and so forth. Usually different colors are widely-used to distinguish the wires. There should be a legend about the wiring diagram to tell you what each color means. Usually circuits with over two components have two basic kinds of connections: series and parallel.
A series circuit is a circuit where components are connected along one particular path, hence the current flows through one ingredient of get to the next one. In a series circuit, voltages add together for all components connected inside the circuit, and currents are identical through all components.Quick Links. Download this manual.

Tech Drawings of the DC-3 1. Tech Drawings of the DC-3 2. Large Tec' Drawings of the DC Tech Drawings of the Li DC-3 'Prop' Management.The same year the German airship Hindenburg crossed the Atlantic, the still-flying-today Douglas DC-3 was introduced to the world.
The DC-3 is widely viewed as one of the most significant transport aircraft in history, due to its massive and long-lasting impact on the airline industry, and aerospace engineering.
I got the chance to interview Ric Hallquist, the retired Chief DC-3 Pilot for Missionary Flights International who flew and worked on the beefy twin engine transport plane for over 30 years. The DC-3 sat and slept 14 passengers in comfort for overnight flights, or 28 passengers for shorter flights. Because the DC-3 was so well-constructed and reliable with remarkable fuel efficiency for its dayAmerican Airlines C.
Smith said the DC-3 was the first airplane that made passenger transport profitable. Even so, of the 10, Douglas DC-3s built, there are an estimated 2, DC-3s still in commercial service all over the globe which includes the C military conversion. The DC-3 named for Douglas Corporation was designed as a significantly improved version of the DC-2, the popular transport plane predecessor, of which were built.
Though the earlier version could seat 28 passengers on short flights, the airline version sold to United Airlines and American Airlines sat 21 and had no sleeping berths. Photo is in the public domain.
The Boeing had a faster cruise speed and a lower fuel burn, due to it weighing less than half as much as the DC-3, but because of the increased fuel capacity of the DC-3, fewer stops were needed, thus less fuel was wasted on a series of climbs. The crew of the DC-3 was generally made up of two pilots and one flight attendant.
The DC-3 also had a modest bathroom in the rear, complete with a small window. The radial engines weighed over a thousand pounds each! The C had been upgraded with more powerful engines giving the plane an additional HP and was refit and reinforced for large cargo shipments. In addition to its ability to haul troops, Jeeps, and howitzers, the C also had remarkable short-field takeoff and landing performance, reportedly being able to take-off from rough fields less than half a mile long, and land in even shorter distances.
The US military had over 10, Cs and their variants built during the war. The US did see another opportunity, however: the Douglas Dakota. Though now retired, he says the DC-3 is an honest, straightforward airplane that will continue to keep you on your toes as long as you fly it. Ric compares the handling of the DC-3 to a giant, over-sized Super Cubor a pick-up truck without power steering.
All that taken into consideration, Ric still believes the Cessna is harder to land! Ric believes the DC-3 has survived and thrived for the past 81 years because it was over-designed. He means that back inthe Douglas Corporation had never built an all-metal airplane this large, and so they took extra measures to make it hardy and dependable.
Ric credits some of the airplanes durability to the construction of its wings. This lead to a more even load-distribution across the entire wing, allowing the DC-3 to withstand considerable amounts of punishment before the wings even hint at an issue. That being said, Ric did tell me about an AD mandating hour wing inspections.
Again, as an old metal plane, a common issue DC-3s should be inspected for is corrosion. As an uncommonly utilitarian airplane Ric says MFI can swap between the passenger configuration- which seats to the cargo configuration in one day it makes sense that the DC-3 would do well in adverse conditions.
The Douglas DC-3 made flying as a form of transportation possible for the masses, something everyone is thankful for. It just takes patience, physical strength, and a lot of time. However, every pilot who flies the Douglas DC-3 has nothing but good things to say, according to Ric Hallquist.
Sohn, Retrieved Flying the Amazing Boeing Thousands of pilots mourn its retirement, but the event also revives fond memories for those that flew one.
