What is a high alpha maneuver?
High-alpha maneuvers are maneuvers performed at slow speeds with high angles of attack, close to a stall, demonstrating the aircraft’s maximum maneuverability at slow speeds. Fighters such as the F/A-18 Hornet dominate in the high-alpha regime, out-turning their enemies at slower speeds.
Where is stress the greatest on the aircraft wing?
The wings are prevented from folding over the fuselage by the resisting strength of the wing structure. The bending action creates a tension stress on the bottom of the wings and a compression stress on the top of the wings.
Is the cobra maneuver useful?
The Cobra maneuver has been used in mock dogfights but there is little to no known documentation of it being used in actual combat. That being said, there is evidence that it was a useful combat move during the third and fourth generations of jet fighters.
What are the four basic flight maneuvers?
The four fundamentals (straight-and-level flight, turns, climbs, and descents) are the principle maneuvers that control the airplane through the six motions of flight. To master any subject, one must first master the fundamentals.
What is aircraft structure stress?
Stresses on the wings, fuselage, and landing gear of aircraft are tension, compression, shear, bending, and torsion. These stresses are absorbed by each component of the wing structure and transmitted to the fuselage structure. These stresses are known as loads, and the study of loads is called a stress analysis.
What are the major structural stresses of an aircraft?
There are five major stresses [Figure 1] to which all aircraft are subjected:
- Tension.
- Compression.
- Torsion.
- Shear.
- Bending.
What is Split S maneuver?
The Split S is an air combat maneuver mostly used to disengage from combat. To execute a Split S, the pilot half-rolls their aircraft inverted and executes a descending half-loop, resulting in level flight in the opposite direction at a lower altitude.
Can the F-22 do a Cobra maneuver?
The maneuver is very stressful & it serves no useful military purpose. The F-22, F-35 & F-18 have demonstrated the ability to do a Pugachev’s Cobra.
What is 9G maneuver?
Under 9G’s, the world appears to shrink until it looks like you’re viewing it through a toilet paper roll. Blood is being pulled out of your head towards your legs and arms, resulting in the loss of peripheral vision.
What is a hammerhead maneuver?
Definition of hammerhead stall : a maneuver in which an airplane pulls up in a vertical climb until it almost stalls and then drops the nose in a wingover so that direction of flight is reversed.
What are the different types of stresses on an aircraft?
There are five major stresses [Figure 1] to which all aircraft are subjected: 1 Tension 2 Compression 3 Torsion 4 Shear 5 Bending
What force pushes the pilot forward in a catapult?
This force pushes the pilot forward into the shoulder strap. Naval pilots flying from aircraft carriers feel the extremes of this type of G force. During a catapult launch, the aircraft accelerates to 160- plus mph in just under two seconds.
What type of aircraft has the highest acceleration force?
fighter jets and high-performance, aerobatic aircraft where the acceleration forces may be as high as 9 Gs. Air race pilots in a tight pylon turn also experience high G-forces, but the important thing to remember is that any aircraft operated in a maximum-performance profile will subject the pilot to acceleration that is greater than the 1 G
What are the forces acting on a plane when it takes off?
These forces are passed from member to member causing bending, twisting, pulling, compression, and shearing forces. As the aircraft takes off, most of the forces in the fuselage continue to act in the same direction; because of the motion of the aircraft, they increase in intensity.
