? End of an era: Here is the NASA-RDE (Rotating Detonation Engine) NASA's recent showcase of a rotating detonation engine (RDE) achieving a long-duration burn has sparked excitement and curiosity within the aerospace community. The fundamental difference between deflagration and detonation lies in the flame front's speed relative to sound. Deflagration moves slower, allowing particles to be pushed and moved by heat and pressure changes, resulting in a fireball. Detonation, however, moves faster than particles can push against each other, creating an explosion due to the immediate and intense pressure wave. This distinction is critical for engine design. Detonations, being more energetic, promise better fuel efficiency and thus longer travel distances on the same amount of fuel. However, controlling a detonation within an engine presents significant challenges. Traditional engines rely on the gradual mixing of fuel and oxidizer, but a detonation's speed leaves no time for such mixing, potentially leading to engine damage or inefficient burning. Enter the rotating detonation engine. Its design includes a donut-shaped combustion chamber, allowing for continuous detonation waves propelled around the chamber. This approach requires precise control of fuel injection and timing to maintain the detonation wave, making the engineering behind RDEs incredibly complex yet fascinating. The potential of RDEs to revolutionize aerospace propulsion by providing more efficient and powerful engines is immense. However, the intricacies of maintaining continuous detonations without damaging the engine or compromising performance highlight the innovation and challenges in aerospace engineering today. #Aerospace #Engineering #SystemsEngineering #NASA #Innovation #RotatingDetonationEngine

A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/anodes. These exist in many forms (see electric propulsion). However, in the scientific literature, the term "plasma thruster" sometimes encompasses thrusters usually designated as "ion engines". Plasma thrusters do not typically use high voltage grids or anodes/cathodes to accelerate the charged particles in the plasma, but rather use currents and potentials that are generated internally to accelerate the ions, resulting in a lower exhaust velocity given the lack of high accelerating voltages. This type of thruster has a number of advantages. The lack of high voltage grids of anodes removes a possible limiting element as a result of grid ion erosion. The plasma exhaust is 'quasi-neutral', which means that positive ions and electrons exist in equal number, which allows simple ion-electron recombination in the exhaust to neutralize the exhaust plume, removing the need for an electron gun (hollow cathode). Such a thruster often generates the source plasma using radio frequency or microwave energy, using an external antenna. This fact, combined with the absence of hollow cathodes (which are sensitive to all but noble gases), allows the possibility of using this thruster on a variety of propellants, from argon to carbon dioxide air mixtures to astronaut urine. Plasma engines are well-suited for interplanetary missions due to their high specific impulse. Many space agencies developed plasma propulsion systems, including the European Space Agency, Iranian Space Agency and Australian National University, who co-developed a double layer thruster.

Ursa Major, a U.S. rocket motor maker, has designed and extensively ground-tested the Draper engine, a significant advancement in hypersonic and in-space propulsion technologies. This milestone, announced in May 2024, provides the United States with a considerable advantage in developing these critical technologies. The Draper engine, with a thrust of 4,000 pounds, utilizes storable liquid fuel and features a closed catalyst cycle architecture, allowing flexibility in fuel choice and operation at varying thrust levels. These characteristics make it suitable for applications such as in-space propulsion, hypersonic target emulation, and nonterrestrial surface landings. The successful development of the Draper engine has profound strategic implications for the United States, particularly in the context of escalating international tensions with nations like Russia and China. Its unique features make it appropriate for maneuverable spacecraft, hypersonic interceptors, and orbital transfer vehicles. Ursa Major plans to join the U.S. government's testing regime shortly, with expectations of obtaining qualification for the Draper engine in 2025 and a possible test flight in 2026. As the company progresses and establishes credibility for the engine's design, it is poised to become a significant player in the U.S. hypersonic and in-space propulsion technologies.

?? ISRO's rocket engines are set to benefit from a carbon boost to increase their payload capacities. The rocket engine nozzles, which play a crucial role in accelerating hot, high-pressure exhaust gases, significantly impact performance in three key areas: thrust levels, specific impulse, and thrust-to-weight ratio. An efficient nozzle design can increase the engine's thrust by accelerating exhaust gases more effectively, leading to stronger forward motion. This also enhances fuel efficiency, known as specific impulse, by maximizing energy extraction from expanding gases, thereby requiring less propellant for the same thrust level. This allows for a lighter rocket for the same payload or a larger payload with the same amount of propellant. Additionally, a well-designed nozzle optimizes the engine's thrust-to-weight ratio by achieving high thrust while minimizing the engine's own weight. Currently, the PS4, the fourth stage of the PSLV, uses twin engines with nozzles made from Columbium alloy. By replacing these metallic divergent nozzles with carbon-carbon (C-C) counterparts, ISRO can achieve a mass reduction of around 67%, which in turn increases the payload capability of the PSLV by approximately 15 kg. This enhancement represents a significant improvement for space missions. #isro #isromission #pslv #gslv #space #spacemission #rocket ISRO - Indian Space Research Organization
