Aerospikes/Plug-Nozzles (created by Aerojet) have the advantage of maintaining opmtimal expansion throughout it's flight regime. Bell Nozzles are generally designed to be optimized for a given altitude range, and can suffer from over (loosing effective thrust) or under expansion (loosing thrust and damaging the nozzle). In liquid fueled engines, they are much more compact, and can be made to vector thrust by trottling individual combustion chambers, dispensing with heavy hydralics.

Aerospikes are a type of nozzle

[@richardmillhousenixon]

@@intothevoid5074 Same with Puff monopropellant engine. It's just the AJ-10 OMS engine from the Space Shuttle, minus the OMS pod. That's also why it's angled like it is, so it can be attached at the top of the Mk3 engine mount while still pointing roughly through the CoM, or at least close enough to where the gimbal can take care of getting it to point through the CoM

[@richardmillhousenixon]

Fun fact: The AJ-10 is also the most efficient hypergolic engine currently operated by the US, and 3rd most efficient operational hypergolic engine in the world

[@Zoomer30]

The "single stage to orbit" shuttle type vehicle that was been developed in the early 90s used an aerospike. The drawback to normal engines is the nozzle. It only has one outside air pressure where it is at peak efficiency. At liftoff, the high air pressure at the ground "pinches" the plume and reduces thrust. At high altitude the very low pressure allows the plume to "bloom" or over expand, also reducing thrust. This is really visible in a Saturn V launch, and also Shuttle launches viewed from the ET cam. Near MECO, the SSME plume fills the whole screen it's so expanded. Aerospike uses the air pressure as the nozzle. So it's always at peak efficiency no matter the pressure altitude.

[@cowboybob7093]

Along *Zoomer30's* line: The perfect balance is when the pressure of the exhaust as it exits the thrust chamber (the bell of a conventional engine) is equal to the ambient air pressure. If exhaust pressure is too low, the exhaust flow will separate from the wall of the thrust chamber before it exits. There are clips of this if you look long enough.. A good place is the SDASM KZbin channel, the early Atlas tests. Because the engine was designed to have the hot exhaust touching the whole way out, when it does not touch it can become unstable. At the other end of the flight is something that cant' be avoided: Venting into a vacuum, the gasses simply cannot equal the extremely low pressure of a vacuum, so some gasses can be seen as exiting apparently perpendicular to the flight path. But the pushing of the thrust takes place somewhere inside the thrust chamber, maybe even at the last plane inside the he bell. The gasses venting away are simply not contained by ambient air pressure like they were a couple of minutes later on the pad. My thought on aerospike is: If it had proven superior, it would have found an application, big or small. This clip made me think of maneuvering thrusters.

[@techsomat5757]

Jeasus f***ing Christ that is the shortest comment I have ever seen

[@brainmind4070]

A full aerospike with isentropic expansion would deliver this. This is not possible in reality, however, as the nozzle would be ridiculously long, and the tip would break off. With a truncated aerospike, it never quite reaches the peak efficiency of a bell nozzle, but it is much more efficient over most of the burn, so overall efficiency is markedly better.

I thought aerospikes weren’t supposed to form shock diamonds due to their high efficiency

[@graegoles8382]

What do you mean? I know litrle about the subject but am interested

[@janpenner2002]

Yep, that is true with perfectly designed aerospikes. Here, the cone is not "curved", meaning it doesn't get more pointy at the end (if you know what I mean😅) that causes the flow to not be pointed straight at the end of the spike. This however makes it cross the flow from the other sides of the spike. And that's why it causes shock diamonds. (The flows cross each other behind the tip, then go away from each other, but that creates a low-pressure zone (aka the shock diamonds) in between them that pulls them in again which causes them to cross again and then it repeats)

[@generationedge6699]

Bro. There has not been enogh research on aerospikes. That's why they form shock diamonda

[@janpenner2002]

@@generationedge6699 umm no that's not the problem. There are aerospikes that don't create shock diamonds. The point is, it's difficult to build one in this size since the tip would get way too hot if it was designed to avoid shock diamonds. So you'd have to cool it and/or use expensive materials and I guess these people here didn't have the resources to do so.

[@generationedge6699]

​@@janpenner2002 Exactly. Because aerospikes have about twice as much surface area to cool than their casual bell counterparts. Virtually, the biggest advantage aerospikes have over bell shaped engines is just optimization at any altitude or pressure. Other than that, in our atmosphere, they fall pretty close to bell-shaped . Bell shaped engines are way easier to cool. Thats why no aerospike has ever made it onto a rocket. Plus, aerospikes are very heavy. So it's disadvantages outweigh its advantages.

There's obviously no improvement between that and a bell nozzle at normal atmospheric conditions the improvement comes within changes to those pressures, where a bell nozzle will be optomized for the "mean atmospheric conditions" that its going to be working its hardest through.
