Wireless Industrial Remote Control Aircraft Refueling System

Aircraft refueling is also known as air refueling or air-to-air refueling and it is a process of transforming fuel from one aircraft or the tanker to another/ the receiver during the flight. It is an important procedure that helps the aircraft to remain stay in the air longer as well as to extend its range or loiter time on station. Aircraft refueling can also be considered as a means to reduce fuel consumption on long distance flights greater than 3000 nautical miles.However, as the process is very difficult or rather complex, it is really hard to maintain this total process manually. So, automated aircraft refueling system or using wireless remote controllers to maintain this whole process is always welcome. Nowadays, by using wireless industrial remote control technology, some unique kinds of automated aircraft refueling systems are being manufactured by the manufacturers.These wireless remote controllers are used widely to refuel aircrafts. These automatic devices are developed specifically for industrial applications that require positive operator-to-machine contact. A wireless trigger-switch is used in these systems in order to send RF command signals to the pump. This Aircraft Refueling Control wireless industrial remote control operating systems unencumbered by cables and wires normally used in 'deadman' fueling operations.One of the chief aspects of these automatic devices is that it allows interference free operation. The system incorporates a secure frequency hopping, spread-spectrum radio link that is virtually immune to outside electrical or RF interference. The spread-spectrum technology, used in these devices, helps the whole system to shutdown during any single loss of signals from the transmitter of the wireless remote controllers.The transmitter, used in these wireless industrial remote control aircraft refueling systems, is highly powerful. Normally the transmitter power is 100mW with a frequency rate of 902-928MHz FHSS and 433.92MHz, 869.7MHz & 2.4GHz radios are also available. However, the transmitter power varies from system to system. The transmitters are rechargeable and they deliver 30hrs of continuous use between charges. Generally 12/24VDC charger is supplied by the manufacturer.Another important feature of this automated refueling device is that it is available with 'Safety Timer' software in order to limit switch closure duration prior to automatic shut-off. This feature also requires periodic trigger pulse by operator to maintain receiver 'on' condition. Many types of Aircraft Automated Refueling Systems are available. The customers can get up to eleven other command functions according to their requirements. It is also available with Modular quick-connect component that allows the system for easy installation and field service. You can also get it with Pre-wired solenoids for your Pneumatic, Hydraulic, or Hose Reel control interface.The wireless remote controllers refueling systems are included with internal 'on card' PCB mounts with normal range up to 500 feet, although, higher power is also available. It is constructed with rugged weatherproof polymer enclosure, ensuring the safety of the systems. Normal rechargeable Lithium Ion battery is used to control the system.

Learn About Aircraft Oxygen System

Learn About Aircraft Oxygen System

Aviation oxygen system is a complex mechanism and requires good maintenance. Generally there are three types of aviation oxygen systems that are being used namely, constant flow, altitude adjustable and altitude compensating. All of them can be found in different aircraft types and have plus and minus points.

Constant Flow Systems is the most common and low cost aircraft oxygen system in aviation industry is the constant flow system. It consists of cylinder, regulator and manifold system. All the oxygen systems have cylinders and constitute of steel, composite metals and aluminum. Most of the regulators used are the diaphragm type and the tank pressure is maintained at 2200 psi or pounds per sq. inch. The constant flow systems provide a uniform output pressure at all altitudes.

It is preferred over other types because of the low cost and very low maintenance. The output of the regulator is 2.5 - 3.0 liters/minute at line pressure of 25 to 75 pounds. It's controlled by the connector attached to the manifold system. Usually factory manufactured oxygen systems in Cessna aircraft use this type of a constant flow system. Portable units of oxygen supply are also based on this system of oxygen supply.

The next oxygen system that are aircraft compatible is 'altitude adjustable oxygen ' system that is like the constant flow system with the additional facility of adjustable control for maintaining the flow. It is done by the control knob for the reading on a gauge that is also calibrated in altitude in symmetry with the aircraft altimeter setting. Though this system is not commonly used in the built in types, portable systems have been incorporating it to a greater deal.

The next system is the 'Altitude Compensating system' which has many similar features of altitude adjustable features but in this system the adjustments are done on automatically. Mooney and Beechcraft use this type of aviation oxygen system and few portable devices for oxygen are also manufactured on these lines. The main disadvantage in this system being incorporated in the aircraft is that the oxygen only starts at a certain height of 8000 to 10,000 feet. In case the oxygen system needs to be started at lower altitude, many times is a problem.

Changing needs give rise to new technology and demand leads to modifications. Aircraft oxygen system has been developed, after much trial and error and now have become compatible with different modes of oxygen supply.

Aircraft Lighting System Fuel Saver

Aircraft Lighting System Fuel Saver

When flying a high-performance sleek aircraft often it is problematic getting the aircraft slowed down. Many super high performance aircraft and gliders have spoilers or speed brakes to help slow them down for landing by increasing drag. For smaller high performance Experimental Composite Aircraft, I propose using this fact to help us power up LED Landing Lights.

I propose we use make a small mechanical flutter energy generator to absorb the vibrations to power up the landing lights using electromagnetic induction technology to charge a capacitor instead of the headlights working off a battery. Currently there are some nifty micro-flashlights being used which you can buy which use a similar technique and are available thanks to the Everlite Flashlight technology research lab. These smaller flashlights work by shaking them for about thirty seconds and shine for about 6 minutes and they shine quite bright since they use a very bright LED light. Here is a link to this home use flashlight:

Here is a quick movie you can watch online to see how this technology works.

I propose we use the engine rumble along with the simple mechanical flutter device to insure we always have power even if we lose the electrical system. It will of course work best and be brightest as you are slowing the aircraft down, as well as assist you in bleeding off the airspeed. Perhaps this is a good way to save energy, save guard in emergency of electrical system failure, assist in slowing down the aircraft and provide the light you need for night landingsl? Think on this.
