战斗机在执行高迎角机动时,飞行员所承受的载荷或“G力”可能会有显著差异,具体取决于所执行的特定机动动作。对于一架F-22猛禽战斗机执行高迎角机动,G力可以在以下范围内变化:
- 中等机动:在较不激烈的高迎角机动期间,G力可能在2到5G之间。
- 激烈机动:在更激烈的高迎角机动中,例如紧急转弯或快速改变方向时,G力可以超过5G,并可能达到9G,这是现代战斗机的上限。
- 持续高G机动:对于持续高G的机动,飞行员可能会承受大约6到9G的G力。F-22的设计能够在维持控制和性能的同时处理这些应力。
飞行员经过严格的训练以承受这些高G力,包括身体素质训练和反G力锻炼,以防止G力诱发的意识丧失(G-LOC)。此外,飞行员还穿戴G力服,这有助于在高G力机动期间维持脑部的血液流动。
The load or “G-force” experienced by a pilot during high-angle-of-attack maneuvers can vary significantly based on the specific maneuver being performed. For an F-22 Raptor performing high-angle-of-attack maneuvers, the G-forces can range as follows:
- Moderate Maneuvers: During less aggressive high-angle-of-attack maneuvers, the G-forces might range from 2 to 5 Gs.
- Aggressive Maneuvers: In more aggressive high-angle-of-attack maneuvers, such as tight turns or rapid changes in direction, the G-forces can exceed 5 Gs and may reach up to 9 Gs, which is typically the upper limit for modern fighter jets.
- Sustained High-G Maneuvers: For sustained high-G maneuvers, the pilot can experience around 6 to 9 Gs. The F-22 is designed to handle such stresses while maintaining control and performance.
Pilots undergo rigorous training to endure these high G-forces, including physical conditioning and practicing anti-G straining maneuvers to prevent G-induced Loss of Consciousness (G-LOC). Additionally, pilots wear G-suits that help maintain blood flow to the brain during high-G maneuvers.
