Falcon HTV-3X - A Reusable Hypersonic Test Bed

Interaction Between Aerothermally Compliant Structures and Boundary Layer Transition in Hypersonic Flow

“…In particular, the Air Force Research Laboratory (AFRL) seeks to enable the development of a Mach 5 to 7 hypersonic cruise vehicle (HCV) with takeoff weight exceeding 300,000 pounds, an unrefueled range of 2,000 nautical miles, and service life on the order of hundreds to thousands of hours [8][9][10][11]. To help satisfy these requirements, the vehicle will use a lifting body configuration with an airframeintegrated propulsion system consisting of a combined cycle (turbojet and dualmode scramjet) engine [11][12][13]. Additionally, a non-ablative thin-gauge metallic thermal protection system is desired in lieu of ablative ceramic insulation [8,9] for the improved serviceability, durability, and potential weight reduction [14,15].…”

Current State of High Speed Propulsion: Gaps, Obstacles and Technological Challenges in Hypersonic Applications

“…These works appear in the form of journal articles, book series, NASA monographs, Air Force reports, textbooks, and periodicals. For example, a limited list of resources examined includes studies attributed to: Hallion, 1-5 Launius, [6][7][8] Bertin, [9][10][11][12][13][14][15] Curran, 16,17 Murthy, 18,19 Jenkins, 20,21 Billig, [22][23][24][25][26][27] Jacobsen, 28 Walker, [29][30][31][32][33] Lewis, [34][35][36][37][38][39] Starkey, 40 Blankson, [41][42][43][44][45] Marren, 46,47 Paull, 48,49 Anderson, [50][51][52][53][54]…”

“…Other U.S. programs that have been devoted to the advancement of scramjet technology consist of the X-51A and FALCON (Forced Application and Launch from Contiguous US). 30,32,33,65 The X-51A WaveRider program is a consortium of the USAF, DARPA, NASA, Boeing, and Pratt & Whitney Rocketdyne. The scramjet engine under consideration uses a 2-D design with the potential of propelling a missile to hypersonic speeds (Fig.…”

Flow Realization in Hypersonic Air Inlet with Spatial Compression

“…В настоящее время все реализованные сверх-и гиперзвуковые входные устройства относятся к первой и второй категориям [1]. В ряде недавних проектов, таких как Falcon HTV, LAPCAT, HIFiRE, HEXAFLY, были приняты или рассмотрены воздухозаборники с компактным поперечным сечением на своих гиперзвуковых транспортных платформах [2][3][4][5]. Интерес к трехмерным конфигурациям воздухозаборников усиливается по мере того, как была доказана возможность реализации гиперзвукового полета в атмосфере и его перспективность для различных практических приложений [6].…”
