  • 4. Lunar Architecture
    4. Lunar Architecture 4.1 Summary and Recommendations As defined by the Exploration Systems Architecture Study (ESAS), the lunar architecture is a combination of the lunar “mission mode,” the assignment of functionality to flight elements, and the definition of the activities to be performed on the lunar surface. The trade space for the lunar “mission mode,” or approach to performing the crewed lunar missions, was limited to the cislunar space and Earth-orbital staging locations, the lunar surface activities duration and location, and the lunar abort/return strategies. The lunar mission mode analysis is detailed in Section 4.2, Lunar Mission Mode. Surface activities, including those performed on sortie- and outpost-duration missions, are detailed in Section 4.3, Lunar Surface Activities, along with a discussion of the deployment of the outpost itself. The mission mode analysis was built around a matrix of lunar- and Earth-staging nodes. Lunar-staging locations initially considered included the Earth-Moon L1 libration point, Low Lunar Orbit (LLO), and the lunar surface. Earth-orbital staging locations considered included due-east Low Earth Orbits (LEOs), higher-inclination International Space Station (ISS) orbits, and raised apogee High Earth Orbits (HEOs). Cases that lack staging nodes (i.e., “direct” missions) in space and at Earth were also considered. This study addressed lunar surface duration and location variables (including latitude, longi- tude, and surface stay-time) and made an effort to preserve the option for full global landing site access. Abort strategies were also considered from the lunar vicinity. “Anytime return” from the lunar surface is a desirable option that was analyzed along with options for orbital and surface loiter.

    Royal Institute of Technology bachelor thesis aeronautics Transport Aircraft Conceptual Design Albin Karlsson & Anton Lomaeus Supervisor: Christer Fuglesang & Fredrik Edelbrink Stockholm, Sweden June 15, 2017 This page is intentionally left blank. Abstract A conceptual design for a transport aircraft has been created, tailored for human- itarian missions along the equator with its home base in the European Union while optimizing for fuel efficiency and speed. An initial estimate of the empty weight was made using historical data and Breguet equations, based on a required payload of 60 tonnes and range of 5 500 nautical miles. A constraint diagram consisting of require- ments for stall speed, takeoff distance, climb rate and landing distance was used to determine wing loading and thrust to weight ratio, resulting in a main wing area of 387 m2 and thrust to weight ratio of 0:224, for which two Rolls Royce Trent 1000-H engines were selected. A high aspect ratio wing was designed with blended winglets to optimize against lift induced drag. Wing placement and tail volume were decided by iterative calculations, resulting in a centre of lift located aft of the centre of gravity during all stages of the mission. The resulting aircraft model has a high wing with a span of 62 m, length of 49 m with a takeoff gross weight of 221 tonnes, of which 83 tonnes are fuel.

Current solutions involve larger, more costly aircraft that carry heavier payloads and have maximum flight durations of less than 36 hours. The presented design would enable a 5.6 day mission with a 10 lb, 100 W communications payload, providing coverage over an area 100 km in diameter. A geometric program was used to size the aircraft, which is a piston-engine unmanned aircraft with a 24 ft wingspan, and a takeoff weight of 147 lbs. The airframe is designed to be modular, which allows for fast and easy transportation and assembly for an operating crew of four to six.

The new category Transport Airships is defined in Appendix C. 2 Existing airworthiness codes FAR P8110-2 of the Federal Aviation Administration of the United States of America and JAR-25 of the Joint Aviation Authorities of Europe have been selected to form the basis of these Transport Airship Requirements (TAR). 3 Certain of the requirements of this TAR, in particular those in Subpart F, call for the installation of equipment and in some cases prescribe requirements for the design and performance of that equipment. These requirements, in common with the remainder of the TAR, are intended to be acceptable to the Authorities as showing compliance, but it should be borne in mind that an importing country may require equipment additional to those in this TAR for operational purposes. 4 The performance requirements of Subparts B and G have been developed on the assumption that the resulting scheduled performance data will be used in conjunction with airship performance operating rules which are complementary to these performance requirements. 5 Terms used in this TAR are as contained in JAR-1, "Definitions and Abbreviations".

  • University of Cincinnati 2016 Engine Design Competition Proposal – the Bearcat 4000
    University of Cincinnati 2016 Engine Design Competition Proposal – The Bearcat 4000 Michael Denton1, Trace Taylor1, Seth Young1, Rich Zelinski1, and Vaughn Bostwick1 University of Cincinnati, Cincinnati, Ohio, 45221 Abstract Advanced materials, higher pressure ratio compressors, elevated turbine inlet temperatures, and shorter combustors have all contributed to major advances in both military and commercial engine developments. The Bearcat 4000 (BC 4000) engine is designed for the replacement of the GE-J85, currently used in the T-38 trainer aircraft. The predicted performance of the proposed afterburning turbofan engine design projects a 28% reduction in specific fuel consumption at cruise conditions compared to the J85, while still meeting thrust requirements over the flight mission. The use of a 0.35 bypass ratio resulted in a smaller core. Consequently, a 44% reduction in weight was estimated based on scaling the engine core to a modern military engine (F119), compared to the GE-J85. The three stage fan and six stage compressor designs were powered by a two stage high-pressure turbine and a two stage low-pressure turbine. A lean burning combustor with a total of nine swirl cups located radially around the annulus was designed from the constraints set by the turbomachinery designers. The use of the afterburner was only needed for supersonic dash and takeoff. Comparative studies between convergent and convergent divergent exhaust nozzle performance indicated a 8% loss in gross specific thrust at Mach 1.3 dash and a 3% loss at takeoff associated with using a convergent nozzle. 1 Student, Aerospace Engineering and Engineering Mechanics, University of Cincinnati, 745 Baldwin Hall, Cincinnati, OH 45221, AIAA Student Member 1 I.

  • Aircraft Design --- Chapter 5: Preliminary Sizing
    5 - 1 5 Preliminary Sizing The preliminary sizing of an aircraft is carried out by taking into account requirements and constraints (see Section 1). A process for preliminary sizing proposed by Loftin 1980 is shown in Fig. 5.1 and detailed in this section. The procedure refers to the preliminary sizing of jets that have to be certified to CS-25 or FAR Part 25. The procedure could in general also be applied to other aircraft categories as there are • very light jets certified to CS-23/FAR Part 23 • propeller aircraft certified to CS-25/FAR Part 25 • propeller aircraft certified to CS-23/FAR Part 23 • propeller aircraft certified to CS-VLA • ... if the respective special features and regulations are taken into account. For propeller-type aircraft the engine thrust T must be replaced by engine power P in Fig. 5.1. Many changes in the equations result from this modification. Fig. 5.1 Flow chart of the aircraft preliminary sizing process for jets based on Loftin 1980 5 - 2 Fig. 5.1 needs some explanation: The blocks in the first column represent calculations for various flight phases. Block 1 "LANDING DISTANCE" provides a maximum value for the wing loading m / S (reference value: mSMTO/ W ). The input values of the calculation are the maximum lift coefficient with flaps in the landing position CLmaxL,, as well as the landing field length sLFL according to CS/FAR. The maximum lift coefficient CLmaxL,, depends on the type of high lift system and is selected from data in the literature. Block 2, "TAKE-OFF DISTANCE" provides a minimum value for the thrust-to-weight ratio ⋅=() ⋅ as a function of the wing loading: TmgfmS/( ) / with reference value: TmgTO/( MTO ).

  • Morphing Aircraft Technology – New Shapes for Aircraft Design
    UNCLASSIFIED/UNLIMITED Morphing Aircraft Technology – New Shapes for Aircraft Design Terrence A. Weisshaar1 Aeronautics and Astronautics Department Purdue University West Lafayette, Indiana 47907 USA 1.0 THE MORPHING CHALLENGE Morphing aircraft are multi-role aircraft that change their external shape substantially to adapt to a changing mission environment during flight.2 This creates superior system capabilities not possible without morphing shape changes. The objective of morphing activities is to develop high performance aircraft with wings designed to change shape and performance substantially during flight to create multiple-regime, aerodynamically-efficient, shape-changing aircraft. Compared to conventional aircraft, morphing aircraft become more competitive as more mission tasks or roles are added to their requirements. This paper will review the history of morphing aircraft, describe a recent DARPA program, recently completed, and identify critical technologies required to enable morphing. As indicated in Figure 1, designing and building aircraft shape changing components is not new. In the past, aircraft have used variable sweep, retractable landing gear, retractable flaps and slats, and variable incidence noses. However, recent work in smart materials and adaptive structures has led to a resurgence of interest in more substantial shape changes, particularly changes in wing surface area and controlled airfoil camber.
