ABSTRACT:Recent technical demonstrations in hostile fire sensing and classification have highlighted the use of costly cryogenically-cooled electro-optical sensors.While capable, these types of sensors come with a higher initial purchase price as well as high life cycle costs per platform.This activity will implement a broad area hostile fire sensing architecture that uses lower cost discrete sens ...

ABSTRACT:The objective of this proposal is to design an inexpensive hypersonic test article with an associated instrumentation package capable of providing measurements necessary for advancing the understanding of aerothermal behavior in the hypersonic flow regime. Significant advances and accuracy validation within multi-physics computational science and engineering (CSE) toolsets (such as comput ...

ABSTRACT:The warfighter needs an accurate and reliable source of Position, Navigation, and Timing (PNT) when GPS is not available. Fortunately, technical advances in navigation sensors and algorithms can reduce dependence on the venerable, yet vulnerable, GPS system. Inertial sensors are becoming increasingly smaller and more accurate. Low cost, powerful embedded computing platforms enable real ti ...

ABSTRACT: S. D. Miller and Associates (SDMA) research team has led the field of research in Opacified Fibrous Insulation (OFI) since 2003.Early OFI prototypes equaled the thermal performance of Thermal Protection Systems (TPS) with MultiLayer Insulation (MLI) using gold-coated shields and vastly reduced cost and maintenance of TPS for hypersonic vehicles.In 2015, OFI prototypes demonstrated improv ...

The Air Force rebuilds and tests many aircraft and ground-power generators each year, involving many hours of loaded run-time. Currently, the generator testing uses resistive load banks, meaning that all of the energy is wasted. To improve facility energy efficiency and to have a positive environmental impact, a regenerative ac/dc load bank is proposed to push power from generator testing back to ...

Boundary-layer transition is important in the design of hypersonic vehicles since it significantly affects the aerodynamic drag and heating.The ultimate goal of this SBIR project is to assemble an easy-to-use, accurate, efficient and robust suite of codes to predict boundary-layer transition on hypersonic vehicles in large-scale wind tunnels and flight.The Phase I objectives are to develop algorit ...

A comprehensive framework for hypersonic boundary layer transition predictions applicable to wind tunnel and free flight conditions is proposed. The distinguishing feature of this transition prediction framework is that it is developed from the ground up allowing full integration of the important transition regions (receptivity region, linear/secondary/nonlinear stability regimes, etc.) and additi ...

ABSTRACT: The proposed effort will focus on the development of the parameterized Navier-Stokes (NS) based ROM for the Dynamic Flight Simulation (DFS) framework. The F/A-18 Active Aeroelastic Wing (AAW) aircraft will be used as the test case to investigate and validate the proposed methods.The background flow solutions under various Mach number and angle-of-attack grid points are first obtained by ...

The proposed effort aims to develop and demonstrate an innovative software tool combining surrogate modeling and image compression techniques for high-speed hyperspectral image extraction from plume signature databases. Salient aspects of the proposed solution are: (1) image compression and data-driven surrogate modeling operate in concert to capture the effects of various parameters (Mach number, ...

ABSTRACT: NP Photonics proposes to develop a high repetition rate, high average power USPL source by taking advantage of our laser technologies based on highly doped glasses. This USPL source has the advantages of high power scalability, compactness, and high reliability.In this Phase I program, we will investigate the feasibility and study the risk to develop a power scalable USPL using our highl ...
