I'm not an engineer. Just a fan. So I ask. With the smaller rocket not seeing as much stress because of its smaller size, would that not mean the stresses it see would last longer because it has less drag? I'm also thinking it would have to pull its shoots at a much higher terminal velocity.

The "Square-cube law" is just a name commonly used to describe the fact that when you increase the dimensions of an object evenly, the volume increases by the cube of the increase in dimension, while the surface area only increased by the square. ie. Take a cube with side length 1m; Its volume is 1m³, and its surface area is 6m².

I shamelessly took cover behind a truck when they (slowly) brought it back to set it down next to XCOR's hangar, after seeing it swing wildly from side to side during translational flight. The Roton's rotor hub punched a hole in the belly of the Chinook when the pilot didn't add power fast enough after setting the Roton down. The day was pretty much a fiasco. Big slung payloads under helicopters can be dangerous.

isnt the model booster too heavy for a drone?

Five electron catches makes a helicopter pilot an ace right...that must be a rule! And I don't know if you mentioned it here Tim (a previous video?) but the real reason they are trying to recover isn't really cost saving, its time to build the another booster which would mean they are worried about meeting demand for launches. And seeing as SpaceX is also trying to offer "bundles" for smaller payloads, there must be a very substantial demand for the smaller launches

It's fun to re-watch these a few years later with knowledge of new directions these companies have taken.

I love these deep dives. Thank you for your hard work!

Dang Tim when did you find time to crank this out?? Mad lad Well done 👍🏻

As a New Zealander, I would love for Rocketlab to nail the recovery on the first try, but in reality, I think there will be a few things to learn in the process. That said, the recovery idea is not a new one, so who knows. It will sure be interesting. Thanks Tim.

@aconite72

4 жыл бұрын

It's a complicated process, but it's far simpler than SpaceX's, so I think the chance of them actually hitting it first try is pretty good. The helicopter is man-controlled, so it's more stable and reliable that way. Falcon 9 was automated top to bottom so there's a steeper learning curve to the landing.

This sort of thing used to be a common practices, early reconnaissance actually used film and the canister would be jettisoned to return to earth. The process works well as long as you put the parachute deployment sensor on right side up (Genesis space probe). It was easier than searching on the ground for it.

To be fair, since the Electron is so much smaller than the falcon nine, hence lighter, it *could* handle the reentry, with the ballute helping, unlike the falcon nine. Furthermore stress on the structure is far less of a problem compared to the f9 due to, again, its small nature. I'm most interested in the logistics in trying to get the chopper close enough to snag a falling booster.

@Hevlikn

4 жыл бұрын

Smaller also means less surface area to drag through the atmosphere, and less thermal mass to prevent critical systems overheating - it's the difference between throwing your phone at the floor or your PC. As Tim mentioned, the rendezvous logistics are pretty much a solved problem - you know which direction the rocket is flying to reach the target orbit, and what it's maximum height is. That'll give you a large, but reasonable area to base your recovery in, and as you get data during descent you can relocate and align with the re-entry. It'll take about the same amount of time from launch -> apoapsis as from apoapsis -> chute deploy (given drag), and then it could spend another few minutes falling with it's deployed chute. If a helicopter can move at 300kmph you get 5km per minute of window. (so 15km if it takes 3 minutes from deploy to splashdown)

@donjones4719

It almost sounds like you're wondering if they will ever have regenerative braking on rockets. So far the problem is kind of similar to trying to capture a lightning strike to charge batteries. It's too much power (heat) too fast. There already is a way to turn heat into power like in spacecraft using RTGs (nuclear batteries). The big difference is the rate the energy is being absorbed. Since you said 'I wonder if we will EVER be able to do this' I'm tempted to say maybe. Who knows what type of breakthroughs the future will bring in materials science etc.
