A Review of Aerospike Nozzles: Current Trends in Aerospace Applications

news.ycombinator.com Cardenas 2025-08-27 07:33:10

The design of rocket nozzles aims to expand the combustion gases until the exit pressure matches the ambient pressure, thereby maximizing thrust. However, ambient pressuredecreases as the rocket ascends, posing a challenge for conventional nozzles, which operate efficiently only at a specific altitude [ 30 ]. By adjusting their flow characteristics to the varying atmospheric pressure, aerospike nozzles offer a significant advantage in this regard. To quantify this impact, the thrust coefficient

The Trump Organization jumped into the smartphone business on June 16, announcing a $499 gold-hued phone and a mobile phone plan, proclaiming on the Trump Mobile website that device would be "designed and built in the United States."
