#mlg #landinggear  How are spinning wheels stop after takeoff, before retraction? 
Boeing 737  100,000 lb 45,360 kg	150 mph 250 km/h 130 kts
Boeing 757	240,000 lb 108,860 kg	160 mph 260 km/h 140 kts
Airbus A320	155,000 lb 70,305 kg	170 mph 275 km/h 150 kts
Airbus A340	571,000 lb 259,000 kg	180 mph 290 km/h 155 kts
The take-off speed ranges and take-off weights of the planes are shown in the table. As you can see, aircraft wheels spin at high speeds. Is there a system that stops aircraft wheels at high speeds after take off?

Although it may differ in aircraft types, in this article, we will answer you according to the commonly used passenger aircraft.
It is quite dangerous to retract the landing gear without stopping the wheels after takeoff. The landing gear compartment contains many vital components for the aircraft. Foreign debris can damage hydraulic lines and components if the landing gear is retracted without stopping the wheels.

How to stop spinning wheels?
For all these reasons, automatic braking system operates immediately after takeoff in modern passenger aircraft. Depending on the type of aircraft (known as the brake metering valve module or de-spin actuator in Boeing), the operating principle of the automatic braking system may vary.

Well, modern planes do not have a braking system in the nose landing gear.

How to stop nose landing gear wheels?
The wheels are stopped in a different way because there is no brake system in the nose landing gear. Parts that stop the nose landing gear wheels are known as nose wheel spin brake linings or the braking pads.

After the nose landing gear is retracted, the wheels are stopped by the effect of friction force. by @gimenezjorge

#aviation #satcom What is The Electronic Warfare System ''HAVA SOJ'' ?
HAVA SOJ system provides to detecting and tracking radar and communication systems of enemy. HAVA SOJ (Stand-Off-Jammer) System confuses and deceives signals of radar and communication systems. Advanced warplanes, laser guided rockets and other ammunition of enemys can be very effective but HAVA SOJ systems can deactivate all of these by confusing electronic signals. Also HAVA SOJ blocks to communicate with each other of enemy troops by confusing signals.
There are these systems in few countries in the world. And few country have been manufacturing this system. HAVA SOJ system is produced and developed by ASELSAN (Military Electronics Industry) and TUSAŞ (Turkish Aerospace Industries, Inc) in Turkey. ASELSAN had manufactured and developed to KARA SOJ systems as firstly. KARA SOJ systems have been integrated to military vehicles. We can think to HAVA SOJ as KARA SOJ integrated to aircrafts.
ASELSAN (Military Electronics Industry) has been producing and developing this system. And TUSAŞ (Turkish Aerospace Industries, Inc) has been leading to integration of system to the aircraft. HAVA SOJ system will be integrated to  BOMBARDIER GLOBAL 6000 BUSINESS JET. The first aircraft of project has 9854 manufacturing number. This aircraft can reach to 984 km/h speed. Range of project aircraft is 11.112 km. This project aircraft can stay throughout 10 hours in the air without refueling. (Other countries can produce these systems as different. And they can use these systems in different types of aircrafts). These factors have been effective when companies choose type of  aircraft for this project.
Companies that developing the system will apply modification to aircraft. Companies will place many consoles and equipments of system to inside of aircraft. Operators will study here. There are many special antennas and many systems on the outer structure of aircraft. For example; There is a big antenna under the nose of aircraft. This antenna is passive ESM/ELINT. Its duty is to providing electronic intelligence. There are SIGINT antennas in front of main landing gears. Its duty is signal intelligence. by @gimenezjorge

#combustible #aeroespace #cohete #spacex  RP-1 (Rocket Propellant) is a fuel used in the propulsion engines of space rockets.  RP-1 is a petroleum derivative similar to kerosene.  It is generally oxidized using liquid oxygen (LOX), with which it burns at 3670 K (3396.85 ° C; 6146.33 ° F), thus producing a large amount of energy for propulsion.  This combination is usually called kerolox.  Rockets like the Atlas, Delta II, Titan 1, Saturn IB, and Saturn V used the RP-1 as fuel in their first releases.  Due to its efficiency, safety and relative low cost, the Russian Soyuz and Angará rockets, and the American Falcon from SpaceX continue to use it today. by @gimenezjorge

#culturageneral #oxigenoliquido #combustible  Old name liquid oxygen, liquid dioxygen, current name (also called LOx, LOX or Lox in the aerospace, subsea and gas industry) is the liquid form of dioxygen.  It has a pale blue color and is strongly paramagnetic.  The density of liquid dioxygen is 1,141 g / cm³ (1141 kg / m³) and it is cryogenic.  Its freezing point is 50.9 K (-222.65 ° C); The boiling point is 90,122 K (-182.96 ° C) at 101,325 kPa (760 mm Hg). In commerce, liquid dioxygen is classified as an industrial gas and has been widely used with certain industrial and medical sectors.  Liquid dioxygen is obtained from natural dioxygen found in air by compound fractional distillation.  Liquid dioxygen has a compression ratio of 843: 9, which is why it is currently used in commercial and military aircraft. by @gimenezjorge

#aviacionmundial #newtechnology #airplane #hipersónico  British-based Reaction Engines has made a technological breakthrough in its efforts to build a plane that can travel to space. The company successfully tested its “pre-cooling” technology, which is critical to cool down compressor delivery temperature when flying at multiples of the speed of sound.

The faster the flow of air into the engine’s intake during high-speed ascent, the higher the temperature. And the heat would rise still further once the airflow is slowed and compressed before entering the combustion chambers -- with the risk of melting the insides of an engine.

The breakthrough test, conducted on March 25 at Reaction Engines’ TF2 test facility at Colorado Air and Space Port near Watkins in the U.S, demonstrated the ability to rapidly chill incoming heated air generated by a General Electric J79 turbojet operating at full military power -- the equivalent temperature experienced at Mach 3.3. The next test will see the J79 operating in full afterburner mode, corresponding to Mach 5. 
Reaction Engines’ pre-coolers comprise of 16,800 pipes made of Inconel 718, a high-strength, corrosion-resistant nickel-chromium alloy. The interlaced metal tubes have walls with a thickness of 40 microns -- thinner than a human hair. This pre-cooling technology can cool air from 1,000°C to -120°C in the space of 1/20th of a second. by @gimenezjorge
