How do combat jets know when to launch flares to counter IR …
2015年8月11日 · There are active systems but they don't work well. I have seen a helicopter in testing suspended from a wire with countermeasures turned on. A missile was fired and the countermeasures didn't even get deployed. This is why they usually keep firing the flares or chaff in known hot spots. Hope that helps.
Are the guns on a fighter jet fixed or can they be aimed?
2017年1月7日 · In dogfight it is usually easiest just to fly the aircraft. Aircraft manufacturing costs versus benefits: likely not worth the extra money. Helicopter-type turret: not very aerodynamic, would cause drag and break up easily by G-forces. Possibly difficult to aim at opponent in dogfight. Fuselage gets in the way while aiming.
What limits the lifespan of helicopters? - Aviation Stack Exchange
2017年4月13日 · Fatigue is a problem that limits, if not the life of the helicopter, at least the working life of some of its key elements, in particular of those subject to strong vibration and made from materials (such as aluminum alloys) that have a fatigue limit. Vibration is the main culprit, and it usually comes from the rotors.
aircraft design - Why do some helicopters have the tail rotor …
2016年9月9日 · When a helicopter is on the ground, a rotating tail rotor could easily injure or kill a person. Mounting it higher up, or covering it up, would reduce that risk somewhat. That would be a bigger concern with larger helicopters that typically have more inexperienced people (passengers, cargo handlers,etc) nearby.

2014年9月24日 · $\begingroup$ If you think the dogfight is over, I’ve got some swamp land in Arkansas to sell you for $20 million an acre. Missiles fail at critical times. Missiles fail at critical times. ROEs prohibit taking a shot without a visual ID on the bogey, stealth aircraft vs stealth aircraft prohibit such attacks, etc.
military - Are there any helicopters with ejection seats? - Aviation ...
2017年8月28日 · Many years ago I read about the Kamov-50 helicopter family * being the first helicopters equipped with ejection seats. And Wikipedia verifies my memory: And Wikipedia verifies my memory: It is the world's first operational helicopter with a rescue ejection system, which allows the pilot to escape at all altitudes and speeds.
How does the efficiency of a fixed wing compare to a rotary wing?
2014年6月3日 · When a helicopter enters a hover, it is using all of its power to provide lift, while a fixed wing aircraft can enter a holding pattern with still only enough power to offset the drag. Comparing the efficiency of lift versus drag of different aircraft shows the lower efficiency of a helicopter. A Cessna 150 has an L/D (lift to drag ratio) of 7 ...
