Ep 12. US Combat Helicopter

Impossible Engineering is a show on Discovery Channel that highlights some of the most complex engineering systems from around the world. In season 10 episode 12, titled "US Combat Helicopter," the focus is on one of the most essential tools in the American military's arsenal: the combat helicopter.

The episode starts with a look at the history of combat helicopters, beginning with the Bell AH-1 Cobra, which was first introduced in the Vietnam War. From there, we move on to the more recent AH-64 Apache, which has played a crucial role in operations in Iraq and Afghanistan.

But the episode isn't just a history lesson. The real meat of "US Combat Helicopter" is the engineering behind these remarkable machines. We hear from engineers who work on the helicopters, as well as military personnel who use them in combat situations.

One of the key components of any combat helicopter is its weaponry, and the episode takes a close look at the AH-64 Apache's gun and missile systems. We see how the helicopter's M230 chain gun is able to fire rounds at a rate of 625 rounds per minute, and how its Hellfire missiles are able to hit targets with pinpoint accuracy.

Another crucial aspect of combat helicopters is their ability to fly in very low-level, nap-of-the-earth flight patterns. This means flying at extremely low altitudes, sometimes just a few feet above the ground, in order to avoid detection and enemy fire. The episode explores how the Apache is able to do this, using design features such as its forward-looking infrared (FLIR) camera, which allows pilots to see obstacles in front of them even in total darkness.

Throughout the episode, we learn about the incredible engineering feats that have gone into making the Apache such a successful combat helicopter. For example, we see how the helicopter's rotor blades are made from advanced composite materials that are able to withstand the rigors of high-speed flight and heavy combat use. We also learn about the way the Apache's advanced avionics systems allow it to operate in a wide range of weather conditions, including in the middle of sandstorms and other harsh environments.

But perhaps the most fascinating part of "US Combat Helicopter" is the glimpse it provides into the psychological side of combat helicopter use. We hear from Apache pilots who describe the incredible feeling of flying such a powerful machine, as well as the intense focus required to fly it successfully in combat situations.

Overall, "US Combat Helicopter" is a fascinating look at one of the most impressive feats of engineering in the modern military. The episode combines historical context, expert interviews, and stunning footage to give viewers a complete picture of what goes into building, flying, and using these incredible machines.
