(hereinafter EXOS or (E.A.S.T. for legal purposes)) is the successor company to Armadillo Aerospace LLC. (Hereinafter AA (the EXOS team)). EXOS acquired AA’s mission critical physical assets in early 2015 to take this technology commercial with the development of the SARGE platform. AA was a leading developer of reusable rocket powered vehicles and continuing the tradition EXOS is immediately focused on suborbital research rockets, with the vision of launching microsatellites and, eventually progressing to autonomous spaceflight. Founded in 2000, AA had an unequaled experience base with more than two hundred test flights spread over two- dozen different vehicles. Projects were undertaken for NASA, the Air Force, and vehicles were flown at every X-Prize Cup event. AA performed the very first flight under the new FAA/AST experimental permit regulatory regime, and made over two dozen additional permitted flights since then, all fully insured and observed by on-site AST personnel. AA (the EXOS team) pioneered the tethered flight test regime in conjunction with FAA)/AST and is the only company in the world to test sounding rockets in this manner. AA also flew the first flight under the Class III waiver, and flew more than twenty-four waivered flights since then at two different locations. In 2011 AA was one of only seven companies selected by the NASA Flight Opportunities Program (aka CRuSR) to provide launches for scientific payload providers on reusable vehicles. AA was also selected by NASA Johnson Space Center to build its Project Morpheus Lunar Lander Terrestrial Analog vehicle and to develop the LOX-LCH4 (Liquid Methane) propulsion technology to power it. Morpheus has now completed thirteen successful flights at Johnson Space Center and Kennedy Space Center ❑ AA also had experience with manned rocket powered flight through its involvement with Rocket Racing Inc and its rocket racer program. AA developed, manufactured, installed and tested the propulsion systems for their T1 and T2 prototypes based on the Velocity airframe and provided launch assistance for more than seventy test flights including the world’s first two rocket plane side-by-side demonstration flight. EXOS is very proud to have been able to reassemble most of the AA team at EXOS and will further refer to the AA “history events” referenced to our EXOS team synonymously to honor them and their continued commitment to this endeavor. It is EXOS’s intention to give credit to John and Anna Carmack for building a team that could carry on the effort, and that, is the mark of any truly great visionary. E.A.S.T.

The SARGE family of vehicles was developed to test a wide range of technologies that EXOS requires for its suborbital vehicles. The SARGE vehicle highlighted in this PUG is based on the successful STIG B platform and predating technologies developed during AA’s lunar lander program. More details follow in the next section. 2. SARGE VEHICLE 2.1. As previously mentioned, the SARGE vehicle is based on tried and proven technologies developed by the AA (the EXOS team) over the past fifteen years. The reliable LOX-Ethanol propulsion module is based on the successful LE23000FC series engines that have hundreds of flights and more than seventy manned flights to their credit. One specific engine has undergone more than one thousand ignition events, including in-air restarts and run for more than two hours. This engine has therefore already demonstrated it is reusable for over 75 SARGE flights to space. The avionics (main flight computer) is in-house designed, developed and manufactured incorporating all modern electronics. The flight safety system associated with this avionics package is also in-house developed hardware that has been flight-tested hundreds of times with 100% reliability. In its fifteen year history, the team has never had a single lost time accident or injury for any reason. AA built the very first VTVL for the NASA / Northrop Grumman Lunar Lander Challenge and is the only company to have flown vehicles in every event through its conclusion. The company won prizes at both levels and was the first company to conduct both a “Level I” and, more arduous, “Level II” mission … Back-to-back three minute flights with precision landing on a simulated lunar surface in less than 150-minutes. As a result of the company’s success in this competition, AA was chosen by NASA Johnson Space Center to build their very first Lunar Lander analog vehicle since the LLRV (Lunar Lander Research Vehicle aka “Flying Bedstead”) developed during the Apollo era. This was subsequently campaigned by NASA under the Project Morpheus banner. Following the successes with the lander program AA opted for an unconventional reusable sounding rocket program, STIG (Suborbital Transport with Inertial Guidance) using the proprietary technologies developed but on a much more capable vehicle. 2.2. SARGE, the successor to STIG, is a reusable sounding rocket based on a 20” (50-cm) diameter airframe. It utilizes the LE23000FC LOX-Ethanol propulsion technology and the proprietary avionics and flight control hardware developed over the prior fifteen years.

Cold gas thrusters (using residual helium pressurant gas) provide attitude control for pitch-roll-yaw, and ultimately pointing capability. The boost profile is nominally full thrust for the entire burn to achieve maximum altitude but, unlike a solid rocket motor, the boost profile can be infinitely modified, if required, by the main flight computer at the expense of reduced altitude. Helium pressurant gas is used to push the propellants into the engine feed system. No pumps are used for simplicity, ruggedness of design and reliability of operation. Thrust can be regulated by operation of the Main Propellant Feed valves controlled by the main flight computer. A separate set of Master Cut-Off valves are controlled by the Watchdog Computer and the Thrust Termination System. The avionics module houses the main flight computer and its power supply. Based on vector inputs from the Inertial Navigation System, an Inertial Measurement Unit (IMU) and GPS, it flies a near vertical trajectory all the way to suborbital space, monitors the health of the vehicle and ensures that the vehicle remains within the Flight Hazard Area. Recovery is provided by a two-stage system. First, a supersonic ballute is deployed together with the nose cone during the descent phase to provide base stable but fast descent through the upper atmosphere and jet stream winds. Then, as the vehicle enters the denser air, a Wamore GPS steerable main chute is deployed which glide-flies the vehicle back to the launch area.

E-mail: [email protected] ABSTRACT Selecting liquid methane as fuel is a prevailing trend for recent rocket engine developments around the world, triggered by its affordability, reusability, storability for deep space exploration, and prospect for in-situ resource utilization. Given years of time required for acquiring a new rocket engine, a national-level R&D program to develop a methane engine is highly desirable at the earliest opportunity in order to catch up with this worldwide trend towards reusing launch vehicles for competitiveness and mission flexibility. In light of the monumental cost associated with development, fabrication, and testing of a booster stage engine, it is strategically a prudent choice to start with a low-thrust engine and build up space application cases.

  • 0.0 a New Way to Look at Things George Nield FINAL
    A NEW WAY TO LOOK AT THINGS by ∗ George C. Nield ood evening everyone. I am not sure how many of you are aware of it, but today is the anniversary of a very significant event G in the development of mankind’s understanding of the Universe. It was on 24 May 1543, that Nicolaus Copernicus is said to have published his most important work, which was titled "On the Revolutions of the Celestial Spheres." Previously, based on the writings of Aristotle and Ptolemy, it had been assumed that the Earth was located at the very center of the universe. Copernicus rejected that approach. Instead, he showed how a model of the Solar System in which the Earth and other planets traveled in orbits around the Sun was better able to account for the observed motions of the heavenly bodies. Although Copernicus did not attempt to explain what would cause such motions, the publication of his heliocentric theory provided a new way to look at things, and it is often hailed as marking the beginning of the scientific revolution. We have come a long way since then in our knowledge of physics, mathematics, and astronomy. At the same time, with the recent retirement of the Space Shuttle, we are currently in the process of undergoing a huge change ∗ Associate Administrator, Commercial Space Transportation, Federal Aviation Administration, Washington, DC, USA. REGULATION OF EMERGING MODES OF AEROSPACE TRANSPORTATION in how we travel to and operate in outer space, and how we think about spaceflight. Ever since the very beginning of the space age, more than 50 years ago, almost every space activity, milestone, and accomplishment has been under the direction and control of national governments, which in the US has meant NASA or the Department of Defense.

  • Cfd Kinetic Scheme Validation for Liquid Rocket Engine Fuelled by Oxygen/Methane
    DOI: 10.13009/EUCASS2019-680 8TH EUROPEAN CONFERENCE FOR AERONAUTICS AND SPACE SCIENCES (EUCASS) CFD KINETIC SCHEME VALIDATION FOR LIQUID ROCKET ENGINE FUELLED BY OXYGEN/METHANE Pasquale Natale*, Guido Saccone** and Francesco Battista*** * Centro Italiano Ricerche Aerospaziali Via Maiorise, 81043 Capua (CE), Italy, [email protected] **Centro Italiano Ricerche Aerospaziali Via Maiorise, 81043 Capua (CE), Italy,[email protected] ***Centro Italiano Ricerche Aerospaziali Via Maiorise, 81043 Capua (CE), Italy,[email protected] Abstract In recent years, greater attention has been paid to green propellants, among those liquid methane is one of the most promising choice. This has also been encouraged by the abolition of hydrazine for its intrinsic human-rating concerns. On the other hand, the adoption of methane as a fuel introduces some issues about modelling. Detailed kinetic schemes are required to properly reconstruct combustion process. This is especially true for rocket propulsion problems, in which the combustion is characterized by high pressure and not stoichiometric mixture ratio. Moreover, detailed scheme may not be feasible for CFD applications, due to high computational cost. For this reason, adoption of reduced schemes is encouraged, even if detailed mechanism description is required. In the present work, a reduced kinetic scheme (HPRB, by CIRA) will be presented for a specific LRE application. Some experimental firing-tests (i.e. FSBB test-campaign) will then be compared with model results, in order to validate the proposed model. 1. Introduction Traditionally, high performance rocket engines have used LOX and hydrogen or LOX and kerosene, while, as such, methane has not yet been used in a commercial launch vehicle.

This paper outlines the development of the main engine for the VTB. Morpheus main engine requirements: 4,200 lbf thrust, 215 sec ISP, a 4:1 throttle range, and a minimum run time of 210 seconds. The VTB is designed to operate with or without active propellant pressurization, so the engines must also be able to operate under stable pressure or blowdown operation. Additionally, the engine must be able to respond to changes in desired thrust very quickly and be insensitive to rapid engine rotation due to gimballing.

This instability usually manifests during low-throttle startup conditions and can propagate through mainstage throttle-up. It has never been shown to start after mainstage throtte-up. – Warm LOX causes transient, self-limiting instabilities that appear as 1T-1L or 1R (with harmonics).
