When I was in the military, we were told to always have a plan for any potential emergency. It wasn’t something that we were told to do on a whim or a whimper. It was to be planned for, prepared, and executed well. The truth is that we are often in a better place because we have a plan.
Helicopters fall into two categories, fixed-wing and rotary-wing. While fixed-wing helicopters have fixed wings that are designed to rotate around a single point, rotary-wing helicopters have rotors that are designed to circle in a circle. These helicopters are often used for air traffic control and, in some cases, are used to rescue people from water.
The helicopter engineering is what happens when you take a helicopter and replace its rotor with a wing. It’s the same principle that an airplane mechanic would use to replace the engine in a plane. So it’s only natural that helicopters be used in rescue missions. The problem is that they are very expensive to build. So when they do come on the market, a lot of those helicopters are built only for military use.
One of the biggest problems with helicopters in rescues is that they are very heavy and very expensive to assemble. Helicopter engineering is great in emergencies because you can save that expensive aluminum frame and rotor from being destroyed in battle and replace it with a lightweight carbon frame and a more efficient engine. But the cost of helicopter engineering has made it almost prohibitive for rescue missions. So instead, a lot of helicopters still use the old aluminum frames and the old engines that just aren’t cutting it anymore.
It seems to be the old frame that is the problem. On Rescue, helicopters use the old frames because they have no way of making the new frames. And even though the new frame is lighter, it is still expensive to make due to the labor involved. So even though they are cheaper, they are still heavy and expensive.
It is difficult to make the new frames, but it is also difficult to make them out of aluminum. A lot of people think the problem is the material, but it is because the frame needs to be a certain size to get the weight right. The old frames are made of aluminum, but the new frames are made of carbon fiber and steel. The carbon fiber is lighter and more cost effective, but the steel is much stronger.
The reason why the carbon fiber is cheaper is because it is. The old metal frames were made of steel and they are very heavy. So people are buying the carbon fiber aluminum frames, which are lighter and cheaper than the old aluminum frames. However, we are still doing all the welding the old way. So we’re still paying almost double the price.
The new aluminum frames also use magnesium, which is a non-allergenic material. It is a little lighter, but it also has a very slippery surface. I just finished a project that used all carbon fiber metal and aluminum, and the metal is very slippery, so I ended up having to weld the aluminum to the carbon fiber as well. As a result of that, I wound up having a lot of aluminum bolts sticking out.
In an era where many companies are making titanium alloys, aluminum alloy, and stainless steel alloys, it’s nice to see aluminum not being used as a mainstay. We hear a lot about alloys, welded joints, etc., but aluminum? We hear a lot about the safety and reliability of aluminum alloy, but the reason I say that is that aluminum is very slippery. And you don’t want to have a helicopter that gets stuck on a mountain of aluminum in a helicopter wreck.
I’m not sure why some people are so interested in aluminum, but all the people I know have aluminum-filled holes in them, so it’s nice to see that.
