Breaking the LAND SPEED RECORD in Kerbal Space Program!

We're back in KSP and this time we're trying to break the land speed record on the runway of Kerbal Space Program. Using a variety of engineering techniques can we beat the land speed record and stop in time before reaching the end of the runway and doing a Hammond?

Matt, you are a very creative, smart, and talented person and your videos bring a lot of joy into my life. Your engineering for roadways and bridges is what one would expect from a seasoned roadway engineer. However, and I say this with all due respect, your aerospace engineering is PAINFUL to watch. Watching you designe optimal roadways would be equal to solving complex quadratic equations, but watching you design a high speed vehicle is equal to watching you fail to solve 2+2.

The reason for the plane moving on the runway at the start (at least from what I remember in Scott Manley's videos) is that the in-game object for the runway is perfectly flat, but it covers a good bit of distance on the planet's curved surface, which makes it act like a downward slope towards the middle part of the runway

It's odd that something heavy would go faster - that's not realistic. Consider pinewood derby cars - the weight doesn't make a difference in how fast it goes - aerodynamics/friction are really just about only factors. I suppose something really light would be affected by air resistance a lot more (like a feather) - but it's not like Kerbal has anything that light...

Intakes are for jet engines, which requires oxygen intake from the atmosphere.

I guess the question is can gimbaled engines keep enough control versus having a control surface. From what's I've seen of actual KSP land speed tests there's always a form of control surface. I'm guessing the lift created just by the body of the vehicle is way too much to keep it on the ground without extra control surfaces.

Kind of picked up this challenge. So far have gotten starts, broken 310, and stopped safely all in the length of the runway. The problem I’m having is between 310 and throttle cut off, it tends to go airborne. Have still managed safe stops and landings, but feel like I don’t merit the challenge win if the vehicle goes airborne, even if only after breaking 310. Note: there are better radial chutes for stopping you than the ones you used.

[@lordknight330]

To turn engines off and others on without messing with thrust, try using action groups. You can set certain actions (like engines turning on/off or airbrakes deploying) to a hotkey.

[@bjornseine2342]

Though if the engine you want to keep running is a solid rocket motor, just throttle to 0 - the Lf/O engines will be "off" and the SRBs will keep going, since they can't be stopped (or throttled) once ignited.

[@icmeric]

To clear up a few terms VAC: The thrust of the engine produced in a vacuum (70,000m above kerbin) ASL: At Sea Level, the thrust produced by the engine at sea level Oxidiser: All rocket engines require an oxidiser as the combustion is performed in a sealed environment and due to the amount of fuel used. Jet engines do not require external oxidiser as they use the oxygen in the atmosphere to burn the fuel Also, in the start you were using the red parachuted which are called 'droge chutes' these are often used to slow a craft down from hypersonic speeds to subsonic speeds so the main chutes can be deployed, in your case a normal chute would be better

[@peka2478]

but he obviously expected to beat 340 m/s, thus supersonic, thuse drogue chutes. See, he planned it all very carefully! ^^

[@icmeric]

@Pe Ka drove chutes are only used in kerbal for looks or for slowing down planes, a normal parachute can still be deployed at supersonic speeds

@DerBlaue that is true. For general re-entry, they are kind of redundant, but here they would be worthwhile (but main chutes would have also been a good idea)

[@apolly07]

ASL: ASL means ‚at sea level‘ Braking: Also if you want to slow down there‘s a BRAKE button on the top in the UI (red button to the right of the current height ASL) and I thought that there was also a keybind for it. If the airbrakes aren’t already in the action you can configure it additionally in the action group menu in the hangar, thats the wrench and hammer symbol to the left of the name. You can also make your own custom action group (activated by the number keys, action group 1 => 1, 2=>2 etc) just click on the thing you wish to activate and you can select what to do. Edit: you found it! But I hope the action group thing helps you… I hope I‘ve helped :) P.S. please look at this RCE!

I would highly recommend sepatrons. Facing sepatron masses (like 2-4 rows of 16 sepatrons around a circle) in opposite directions gives you absolutely massive thrust. You can use it to accelerate and break. Lead with a nosecone attached to a decoupler so when you want to brake you have thrust exhaust. Then have sepatrons facing backward in rings surrounded by a payload or faring. Then have your control area e.g. cockpit or computer in the middle. Then create another payload shell to streamline a second set of sepatrons with a hole in the rear for thrust exhaust
