China has a rich history in rocketry. It’s even found its place into Chinese legends with the wonderful tale of Wang Tu‚ who allegedly strapped himself to a chair adorned with rockets to experiment with rocket flight. The story goes that he launched and was never seen again! More recently however‚ a Chinese company has claimed to have launched the ‘World’s most powerful solid rocket’ capable of producing 600 tonnes of thrust and carrying 6‚500kg into low Earth orbit.  The earliest rockets were made using solid propellants‚ typically materials like gunpowder. The predecessors to modern rockets were used in warfare by the Chinese‚ Indians‚ Mongolians and Persians as far back as the 13th Century. During the 20th Century‚ liquid propellants were introduced which offered far more control and efficiency but solid rockets are still used today chiefly due to the ease of use and longevity of the fuel when in storage.  The Chinese aerospace company Orienspace has just launched Gravity-1 a solid fuel propelled rocket. The launch‚ from a modified cargo ship in the Yellow Sea‚ just off the coast of Haiyang City has sent three Yunuao-1 meteorology satellites into orbit. Before take off‚ the short and stubby rocket stood 30 metres high and weighed in at 400 tonnes. Unusually for modern rockets‚ Gravity-1 has three core stages and four boosters‚ all powered by solid fuel. Many modern rockets have a combination of fuel types or favour liquid propellent due to its controllability. In addition to the engines‚ it has flexible swinging nozzles to aid in flight control. One of the stages has been designed so that it can be adjusted to accomodated liquid fuel to improve its payload capacity.  It’s not uncommon now to see ships involved in space exploration. Space X has demonstrated this with the landing of its Falcon-9 first stage enginges. The Chinese teams have favoured sea based launch aboard a converted cargo ship because it offers greater flexibility. The weather has often forced launches to be cancelled so a ship based launch gives mobility and a greater chance of success. A SpaceX Falcon 9 rocket carrying the company’s Crew Dragon spacecraft is launched from Launch Complex 39A on NASA’s SpaceX Demo-2 mission to the International Space Station with NASA astronauts Robert Behnken and Douglas Hurley onboard‚ Saturday‚ May 30‚ 2020‚ at NASA’s Kennedy Space Center in Florida. The Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. The test flight serves as an end-to-end demonstration of SpaceX’s crew transportation system. Behnken and Hurley launched at 3:22 p.m. EDT on Saturday‚ May 30‚ from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to low-Earth orbit for the first time since the conclusion of the Space Shuttle Program in 2011.

After all‚ the solid rockets of NASAs Space Launch System can deliver 1‚632 tonnes of thrust. Regardless‚ it’s great to see another country investing further in rocket technology and it will be interesting to see how this unfolds in the months and years ahead.

The term space plane conjurs up all sorts of images and NASA‚ with their new X-59 (even the name sounds mysterious) they have definitely not dissapointed. Their new quiet supersonic aircraft has been designed to minimise the sonic boom it creates when it crosses the speed of sound. It will fly at 1.4 times the speed of sound and is set for its maiden flight later this year.  The plane is the result of a joint project between NASA and Lockheed Martin and it has a simple yet ambitious aim. The dream is to revolutionise air travel by producing a new generation of commercial jets that can travel faster than the speed of sound. It’s important to note that these will be the next generation of supersonic aircrat because Tupolev TU-144 (maiden flight 31 Dec 1968) and Concorde (maiden flight 2 March 1969) were the first.  Concorde (Image Credit : Eduard Marmet) Supersonic flight is the ability to fly at speeds in excess of the speed of sound. The value for the speed of sound varies based on air density but at sea level‚ it is 1‚224 km/hour. Fly slower than this and the flight is subsonic‚ fly faster and it goes supersonic. Aircraft that break the sound barrier produce the famous sonic boom but this does not occure at the moment an object crosses the sound barrier.  The sonic boom‚ which is the effect of compressed shock waves‚ is a continuous sound that occurs all the time the aircraft travels faster than sound. To observers on the ground‚ you only experince the boom when the pressure wavse pass over you. The sound can be quite distressing so the X-59 hopes to address the disturbance that it causes.  The design of the X-59 looks like it is straight out of a science fiction movie. It is 30 metres long and 9 metres wide. It has a thin tapered nose which takes up about a third of the overall length and it is hoped it will significantly break up the shockwaves that create the sonic boom. Because of the design and the long nose‚ the pilot sits about half way along making it difficult to get a suitable forward view out of a window. To address this‚ high resolution cameras feed a signal to 4K monitors in the cockpit as part of the eXternal Vision System.  Concorde was decomissioned in 2003 having flown for 27 years. Since then‚ we have been limited to subsonic flights and ocean crossing lasting many hours. In comparison‚ Concorde could complete a trans-atlantic crossing from JFK to Heathrow in a little under 3 hours while today’s jets takes more like 7 hours. If the test flights of X-59 later this year are a success then maybe we can all look forward to faster travel times around the globe in years to come.  Source : Lockheed Martin Reveal X-59 Quiet Supersonic Aircraft The post Shhh‚ NASA Reveals its New Quiet Supersonic Aircraft appeared first on Universe Today.
