\nCheaper space access<\/p>\n
Is it an aircraft? Is it a rocket? No, it\u2019s the Mk-II Aurora\u2026and it\u2019s a spaceplane. Although, Will Austin, the flight operations lead and senior flight test engineer for Aurora at Dawn Aerospace simply describes the aircraft as\u2026 an aircraft.<\/p>\n
However, an Aurora test flight is not a normal flight. The remotely-piloted, rocket-powered aircraft takes off from a runway in New Zealand and transitions into a vertical position, whereupon it thrusts upwards into the atmosphere. The 16ft (4.8m) long, delta-winged aircraft then glides back down to land horizontally on the runway. A flight lasts about 30 minutes.<\/p>\n
Not a regular aircraft then. But Austin\u2019s plain nomenclature is characteristic of the everyday way Aurora\u2019s flight test program is being run. The first aircraft, the Mk-II A, started as a low speed, low altitude technology demonstrator, but is now routinely flying to low supersonic speeds, carrying payloads for customers and flying twice a day. Dawn Aerospace is progressing rapidly toward its ambitious target of producing a reusable spaceplane, capable of carrying payloads to suborbital altitudes multiple times a day.<\/p>\n

\nCheaper space access<\/p>\n
Dawn Aerospace has achieved 62 flights<\/a> with the first iteration of the Mk-II Aurora since August 2021. The next flight test campaign is planned to start this month and will run for several weeks.<\/p>\n The next version of Aurora under development, the Mk-II B, has concluded the design phase, and production is underway. The Mk-II B\u2019s maiden flight is planned for the end of this year. Speaking from Dawn\u2019s offices in Christchurch \/ \u014ctautahi, Austin says, \u201cThe Mk-II B is a significant evolution from the Mk-II A. But the B is still a technology demonstrator. We are using it to take the steps we need to make higher performing spaceplanes and prove capabilities along the way.\u201d<\/p>\n The Mk-II B Aurora has an MTOW of 1,000 lbs (450kg). It can carry a 13 lbs (6kg) payload to the edge of space (100km) at speeds of beyond Mach 3.0. Target applications include scientific research, Earth observation, microgravity experiments, and defense.<\/p>\n Dawn, which also has offices in the Netherlands, wants to provide a low-cost, high-frequency alternative to traditional space access. While a rocket will go high and fast to deliver a payload, it won\u2019t return to Earth in one piece. This single-use nature of most rockets increases costs and mission complexity considerably, holding back the exploitation of space. Dawn Aerospace sees business opportunities in reducing the cost of reaching orbit. Unlike larger firms such as SpaceX, Blue Origin and Sierra Space, it wants to create a niche in delivering smaller payloads.<\/p>\n \u201cDawn is fundamentally a space transportation company,\u201d says Austin. \u201cTo achieve this, we are leveraging a lot from aviation, particularly in terms of frequency and reliability. That drives a lot of our design decision-making.\u201d<\/p>\n Infrastructure\u2019s importance<\/p>\n The Aurora spaceplane is being developed with an emphasis on \u201creusability, a short turnaround time, and maintainability,\u201d says Austin. Inevitably, this means design decisions have been made that may impact performance but improve operability. The Mk-II Aurora has typical tricycle landing gear undercarriage, which results in additional mass and complexity, but allows for landing on ordinary runways and reusability.<\/p>\n Equal importance is being given to Aurora\u2019s CONOPs and infrastructure considerations. Rockets usually require a lot of specialized ground infrastructure and the closure of airspace when they launch. \u201cMost aerodromes and airports already have everything the Mk-II Aurora needs. If we\u2019ve got the airspace approval from the regulator, we can operate,\u201d says Austin.<\/p>\n Dawn has cultivated a close partnership with the Civil Aviation Authority of New Zealand<\/a> and the New Zealand Space Agency and operates the Aurora under Part 102 and High-Altitude Vehicle licenses. This enables Aurora to conduct supersonic flights in New Zealand to high altitudes without needing to close large areas of airspace. <\/p>\n \u201cI cannot say enough good things about the regulators here, they have a real enthusiasm for what we are doing,\u201d Austin says.<\/p>\n \u201cDespite there being a rocket engine for propulsion, we pushed hard to be licensed as an aircraft, so we can fly when we like, how we like and integrate with other airspace users. It is a vital part of rapid reusability.\u201d<\/p>\n Jet to rocket propulsion<\/p>\n Early flight testing with the Mk-II A focused on proving the fundamentals with two jet engines fitted, while the rocket engine was being developed in parallel, in-house.<\/p>\n Austin, who joined Dawn in 2021, was part of the spaceplane team from the start: \u201cEarly flight testing was about the basics \u2013 making sure the airframe won\u2019t fall apart and that the avionics is all communicating properly, with the pilot in the loop controlling it. We had the pilot practice engine-out glide landings, because we knew with rocket engine flying there wouldn\u2019t be a chance to stick the landing a second time. The pilot has to be able to nail it every time.\u201d<\/p>\n The pivotal moment in Aurora\u2019s development so far has been the switch over from jet to rocket-powered flight. For the flight test team this meant working with new propellants and an in-house developed rocket engine.<\/p>\n \u201cThe performance of the aircraft went through the roof,\u201d Austin says. \u201cWe went from a speed limit of 200 knots to unlimited, with the ability to go supersonic vertically. But the regulator wouldn\u2019t allow that instantly, we had to build up the flight test program incrementally.\u201d<\/p>\n Senior flight test engineer and flight director for the early flights and first rocket-powered flights was Tim Dutton from the UK, an ETPS graduate who Austin acknowledges had a big influence on the program and team. \u201cHis contributions from applying principles he had learnt from his previous testing and experience helped guide the testing philosophy, and really set us up for success,\u201d he says.<\/p>\n Controlling the variables<\/p>\n The team uses classic flight test methodologies, expanding the aircraft\u2019s flight envelope and building capability in \u201cbite-sized chunks\u201d. However, Aurora\u2019s rapidity makes controlling variables difficult. \u201cFor example, you can\u2019t expand the altitude or test the range of the C2 link without increasing speed, due to the way the rocket engine operates,\u201d Austin says.<\/p>\n \u201cNormally you want to try and constrain as many variables as possible and only alter one at a time, but the nature of how fast Aurora moves means you have to expand many things at once. We do our due diligence early on to make sure that if we expand altitude, speed, g and C2 link range in quick succession, it\u2019s safe to do so. We do analysis before we leave the office \u2013 the systems engineering team run Monte Carlo simulations, including factoring in for the different forecast winds on the day.<\/p>\n \u201cEarly on, when we were expanding the speed envelope, we went in Mach point-one increments, just to show a decent leap. By taking that step, we knew it would be an altitude leap of about this, and it will be a C2 link range of about this, and so on.\u201d<\/p>\n Surprisingly, the unmanned nature of the aircraft causes challenges. Austin explains: \u201cThe risk to personnel is lower, but the complexity of the aircraft is higher, because you have the C2 link in the mix. The latency involved with the uplink and downlink, a pilot on the controls and an FPV camera over the downlink \u2013 the complexity of those components requires us to do a lot of planning and make trade-offs.\u201d<\/p>\n Normal benefits<\/p>\n Success in managing the variables and complexities can be seen in the fact that the team has needed just one Aurora prototype \u2013 although Austin admits there are a number of unexpected lessons that the team has encountered. He also points to the routine way in which the aircraft now operates, with the team running the first payload flights for customers last summer<\/a>.<\/p>\n Austin says, \u201cCracking the sound barrier was a pivotal point, but doing it multiple times means it has become a benign event within the team, which is a good place to be. By the fourth payload flight, it had all become more routine. We just go through what they need to. The team and the vehicle have both matured.\u201d<\/p>\n Austin talks effusively about the people at Dawn and credits the progress being made on the Aurora program to them and the way the company is set up: \u201cThe most important thing I\u2019ve learned is to value your team. Investing in the team is key to the success Dawn has seen to date,\u201d he says.<\/p>\n \u201cI can sit here and talk about the technology we are developing, the nature of the rocket engine, the vehicle itself or even the regulatory work that\u2019s been done \u2013 it\u2019s all impressive \u2013 but it always comes back to the team and talented individuals we have.<\/p>\n \u201cWe also don\u2019t have the luxury of having enormous, siloed teams. My airframe lead and avionics team lead double up as safety officers for flight operations. So not only are they in the thick of the design, but I take them out flying and they are supporting from a safety point of view.<\/p>\n \u201cThis means people know the entire operation end-to-end. I can go into the office and grab a design engineer and stick them in Mission Control, and do flights with full trust.<\/p>\n \u201cThe other benefit is that when it comes to the next vehicle, they\u2019re in the best position to make the right design decisions to achieve a fast turnaround time.<\/p>\n \u201cThat\u2019s a super powerful thing. You are not just a design engineer you are an engineer that does design, build, test, operate, even maintain \u2013 the full loop.\u201d<\/p>\n Future targets<\/p>\n Looking forward, Austin says breaking the K\u00e1rm\u00e1n line into space will be a key milestone for the company. Personally, he is also eagerly anticipating the first flight of the Mk-II B.<\/p>\n The Mk-II B will externally look very similar to the Mk-II A and only be slightly larger. However internally, there are a number of changes. The propellant tanks will be optimized so the aircraft can carry significantly more fuel and oxidizer, so that the engine can produce more thrust. The Mk-II B will also have reaction thrusters for out-of-atmosphere control. \u201cA lot of the improvements are from the Mk-II A,\u201d Austin says.<\/p>\n Once suborbital access to microgravity multiple times a day is flight tested, numerous new opportunities should open. Carrying a payload to suborbital altitudes in the morning, landing and letting the customer make some tweaks and changes, then returning to suborbital altitudes in the afternoon, is a capability Austin says will be unique globally.<\/p>\n Delivery of Aurora to Dawn Aerospace\u2019s first customer, Oklahoma State in the USA, is planned to happen in 2027. This will be another key milestone and proof that an ordinary approach to extraordinary flight testing is the best way.<\/p>\n A flying day out<\/p>\n A typical day for Will Austin, senior flight test engineer for the Mk-II Aurora at Dawn Aerospace starts early in the office, where he does last-minute weather checks before heading out for an hour drive to the T\u0101whaki National Aerospace Centre.<\/a><\/p>\n On site, a team of up to 15 people will split into smaller groups either pre-flighting the aircraft, or setting up equipment such as the Mission Control. A flight crew briefing is followed by propellant loading \u201cThe engine starts, there\u2019s ten seconds to rotate from engine start. There\u2019s a two-minute climb to altitude. And then for the remainder of that mission, when we roll out wings level at altitude, we can be airborne for 20 to 25 minutes on the glide coming back, and we\u2019ll be doing test points.<\/p>\n \u201cThe pilot performs a glide landing similar to the Space Shuttle. There\u2019s a split rudder on board that is used to control the energy. The Aurora glides in, flares, touches the gear down, and just rolls out on the runway.<\/p>\n \u201cIf there is a payload flight it is out of the aircraft and back to the customer within an hour. So they can do whatever analysis they want and have rapid access to both their payload and data.\u201d<\/p>\n \u00a0<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/05\/DawnMk-IIAuroraGlentannerRunway2.jpg.optimal.jpg\")
