Is there a possibility of an aircraft reciprocating not to harness the ambient air as its cooling air?

This chapter covers the primary systems found on most aircraft. These include the engine, propeller, induction, ignition, as well as the fuel, lubrication, cooling, electrical, landing gear, and environmental control systems.

What are the common defects found in the aircraft during inspection?

Airframe defects are generally of three types: cracks, disbonding and corrosion. On the other hand, visual inspection of aircraft components and systems finds wear, fatigue, interference, corrosion and accidental damage.

What is the force that limits the performance of an aircraft?

Weight Control The force of gravity continuously attempts to pull an aircraft down toward Earth. The force of lift is the only force that counteracts weight and sustains an aircraft in flight. The amount of lift produced by an airfoil is limited by the airfoil design, angle of attack (AOA), airspeed, and air density.

What are the conditions that inhibit thermal Wai from operating when auto or on is selected in the cockpit?

With auto or on selected, the operational mode is inhibited if any of these conditions occur: Airplane on the ground (except during an initiated or periodic built-in test equipment (BITE) test) Total Air Temperature (TAT) is more than 50 °F (10 °C) and the time since takeoff is less than 5 minutes.

At what angle does a plane stall?

around 15°
A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. This angle varies very little in response to the cross section of the (clean) aerofoil and is typically around 15°.

Why are aircraft engines horizontally opposed?

The horizontally opposed 4 and 6 cylinder engines are much easier to package in the nose of an airplane and allow the plane to be more aerodynamic. Also, radial engines aren’t terribly smooth unless they have 7 or more cylinders, which is more complexity and power than a typical general aviation aircraft needs.

What are the two things that needs to be checked when performing an on aircraft inspection?

Check for a current weight and balance report, and the current equipment list, current status of airworthiness directives for airframe, engine, propeller, and appliances. Also, check the limitations section of the manufacturer’s manual to verify the status of any life-limited components.

What is chafing aviation?

Chafing. (as applied to visual inspection of aircraft components) Chafing: a condition caused by a rubbing action between two parts under light pressure that results in wear.

Does forward cg increase stall speed?

The effect of forward CG is to increase tail-down force, main-wing loading, and the stalling speed. The tail-down force opposes wing lift and increases effective weight. As the CG moves rearward, less tail-down force is required and the stalling speed decreases.

What is de icing system in aircraft?

Deicing fluid, a mixture of a chemical called glycol and water, is generally heated and sprayed under pressure to remove ice and snow on the aircraft. Pilots temporarily disable the aircraft’s ventilation system during the deicing/anti-icing process to prevent fluid fumes from entering the cabin.

What is anti-icing in aircraft?

Anti-icing systems are designed for activation before the aircraft enters icing conditions to prevent the formation of ice. Most anti-ice systems rely on heat to evaporate the liquid water when it strikes the protected surface. In turbine-powered aircraft, engine bleed air is commonly used to supply the required heat.

What are the advantages of laser weapons?

They provide speed of light “flyout” time and have deep magazines – as long as you have a power source, you can fire the laser and hit a target immediately. Lasers also have a very low cost per shot, so it makes sense to use them against low-cost threats like drones.

Are high-energy lasers five years out?

Longtime skeptics of high-energy lasers often say, ‘the technology is five years out… and will always be’. The DoD and defense industry have invested in laser weapons development for 40 years, in anticipation of a transition to troops that has yet to happen.

What is the DoD doing with laser weapons?

The DoD and defense industry have invested in laser weapons development for 40 years, in anticipation of a transition to troops that has yet to happen. Then, between 2017 and 2018, we demonstrated our high-energy laser weapon system, or HELWS, for the U.S. Air Force and the Army, shooting down multiple drones.

How can the defense industry leverage fiber laser technology?

The material processing industry uses fiber lasers to accurately cut, drill and weld anything from car parts to computers. Meanwhile, most voice and data communications travel through fiber optic cables. This has created an over $2-billion-dollar commercial fiber laser industry that can be leveraged by the defense industry.
