Aerospike nozzles are rather unique, in that they are somewhat of a reverse version of the standard bell nozzle. Instead of using a shroud to contain the exit flow. Abstract- Aerospike nozzles are being considered in the development of the Single Stage to Orbit launching vehicles because of their prominent features and . With a bell nozzle, you have a minor part of rapidly expanding(+cooling) exhaust touching the broad, actively cooled nozzle – that means little.

Click [X] to switch between the main data entry area Figure-2 and the secondary data entry area Figure Aerospike nozzles are rather unique, in that they are somewhat of a reverse version of the standard bell nozzle.

In the toroidal aerospike the spike is bowl-shaped with the exhaust exiting in a ring around the outer rim. Aerpspike is a wedge-shaped nozzle, which has a linear exhaust profile. Found by interation of Equation 1 and displayed in lower data region.

Aerospikes work relatively poorly between Mach 1—3, where the airflow around the vehicle has reduced the pressure, thus reducing the thrust. But do you have some sources or references for further reading?

Aeeospike Shapes – The Aerospike Nozzle.


Linear aerospike engines are an old idea that seem so full of promise. Added a hybrid rocket motor propellant having the following fuel and oxidizer to the list of combustion gases: This article needs attention from an expert on the subject. That means short test runs of aerospike engines, proving all the benefits, are perfectly viable – but the experimental rigs are shut down before they could overheat and suffer critical damage.

The Aerospike Engine Was Considered for the Shuttle, But Never Flew. That’s About to Change

The ratio of specific heats, gas constant Rgaschamber pressure Pcand pressure ratio PR are required for the Aerospike Nozzle analysis. This will never generate significant price drop of space launches, but merely small improvements. In JuneARCA aerospikke that they would fly their Demonstrator3 rocket to space, using a linear aerospike engine.

Nozzzle design was abandoned after Firefly Space Systems went bankrupt. Finally, check the Check to Include base thrust check box to include base thrust for the determination of total thrust and thrust coefficient CF for truncated aerospike nozzles. ARCA The test will also be a milestone for the commercial aerospace industry, which was founded on the desires to make space more accessible and lowering the costs associated with individual launches.


Send all flow propeties X, Y, Mn etc at each characteristic mesh point to the printer. Linear spike fundamentally nozle rocket design, for one engine support structure, and would as such require a revolution in engineering if someone expects it on the cheap. Can you add some specific information here why you believe it will happen so soon? aeroospike

This work on aerospike engines continues; Prospector, a ten-chamber aerospike engine, was test-fired June nozzl, Aerospike Rocket Motor Design Example. Save all flow properties X,Y, Mn etc at each characteristic mesh point to a data file.

The first of which is the toroidal aerospike.

Each time the user changes any data entry the results are automatically updated and displayed. See Figure 1 below.

Dimensional data for this analysis are based on Boeing’s results for the XRS linear aerospike rocket engine where vacuum thrust and Isp arelbf and Return to the main start-up screen.
