Fine Braided Tungsten Reinforced Ceramic Composites for Ultra Sharp Structures

Phase 1 SBIR

Agency: Navy
Topic: N142-119
Budget: 01/01/14 - 12/31/14
PI: Mr. Kent W. Buesking

Future hypersonic vehicles will be required to fly extended, long term trajectories where the bod-ies must exhibit high lift-to-drag (L/D) ratios. The need for reduced drag means that the nosetips and leading edges must have small radii, shallow wedge angles, and be erosion resistant. Desira-ble dimensions include a nose radius on the order of 0...

Innovative Interlaminar Mode I and Mode II Fracture Toughness Test Methods for Ceramic Matrix Composites

Phase 1 STTR

Institution: Southern Research Institute

Agency: Navy
Topic: N13A-T008
Budget: 08/15/13 - 03/15/14
PI: Craig Iwano

It is critical to the safe use of ceramic matrix composite components that information on the fracture toughness of these materials be available, in order to allow an assessment of the likelihood for crack growth. Although Military Standards and American Society for Testing and Materials both serve as resources for room and elevated temperature ...

Innovative Nosetip Materials and Designs for Hypervelocity Projectiles

Phase 1 SBIR

Agency: Navy
Topic: N131-071
Budget: 05/06/13 - 03/07/14
PI: Mr. Kent W. Buesking

The Navy is developing high speed projectiles for a variety of missions including ship defense, surface fire support, and prompt global strike. Inertial loads and high muzzle velocities impose severe operational conditions on the nosetips and suggest they should be made from refractory metals. While metals provide sufficient density for aerodyna...

Improved Foreign Object Damage Performance for 2D Woven Ceramic Matrix Composites

Phase 1 STTR

Institution: University of Dayton

Agency: National Aeronautics and Space Administration
Topic: 12-1-T12.01
Budget: 01/01/13 - 12/31/13
PI: Edward Klock-McCook

As the power density of advanced engines increases, the need for new materials that are capable of higher operating temperatures, such as ceramic matrix composites (CMCs), is critical for turbine hot-section static and rotating components. Such advanced materials have demonstrated the promise to significantly increase the engine operating temper...

Calculation of Effective Material Strengths for 3D Woven Hybrid Preforms and Composites

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-1-H7.01
Budget: 01/01/13 - 12/31/13
PI: Kerry Hopp

Current NASA programs, such as Adaptable, Deployable Entry and Placement Technology (ADEPT) and Woven Thermal Protection Systems (WTPS) are looking to fill a gap in ablative TPS for future missions to Venus and Saturn, human missions beyond Lunar, and Mars Sample Return Missions. Both of these programs rely on the use of 3D woven carbon fiber p...

Test Methods for the Determination of Anisotropic Compliances in 3D Woven Preforms for Ablative TPS

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-1-H7.01
Budget: 01/01/13 - 12/31/13
PI: Craig Iwano

Based on the recent success of the Mars Exploration Program and the Mars Science Laboratory mission, NASA has a desire to expand on the technology developed under each effort in order to increase future mission capabilities, namely an increase in payload capacity for entry to Mars, Venus and other Outer-Planets. Such a goal requires an innovativ...

Low-Erosion and Affordable Nozzles for Advanced Air-to-Air Missiles

Phase 1 SBIR

Agency: Navy
Topic: N121-014
Budget: 06/06/12 - 11/05/12
PI: Craig Iwano

One of the main drivers in the design of nozzles for advanced air-to-air missiles deals with erosion caused by combustion gases. Erosion can happen by melting/sublimation, oxidation and mechanical abrasion depending on the nature of the propellant. Current de Laval nozzles for air-to-air missile applications consist primarily of structural, ther...

Validated Design Model of Lightweight Contoured Sandwich Structure for Aircraft Components

Phase 2 STTR

Institution: University of Maryland

Agency: Navy
Topic: N10B-T050
Budget: 05/21/12 - 11/21/13
PI: Derek Caputo

Navy aircraft employ components that are contoured for aerodynamic performance and made of composite sandwich structures for high strength-to-weight ratio. Many of these components presently use honeycomb cores surrounded by thin high strength face sheets. While honeycomb is used extensively, it can be difficult to form to contoured shapes, must...

Alternative Fabrication Designs for Carbon-Carbon (C-C) Nozzle Extensions

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 11-1-X2.01
Budget: 01/01/12 - 12/31/12
PI: Ms. Tiffany Boarts

In order for carbon-carbon nozzle extensions and exit cones to serve as practical, low cost components for future Earth-to-Orbit propulsion systems, it is necessary to develop alternative fabrication methods coupled with proven design and analysis tools. Two-dimensional (2D) C-C components are typically less expensive and potentially lower weig...

Lightweight Composite/Hybrid Structures with Enhanced Properties

Phase 1 STTR

Institution: Missouri University of Science & Technology

Agency: Air Force
Topic: AF10-BT27
Budget: 12/01/11 - 09/01/12
PI: Craig Iwano

ABSTRACT: Future hypersonic vehicles, like X-43 and X-51 derivatives and Falcon HTV-3, will require advanced strategies for thermal protection systems (TPS) and methods of structural integration. The goal in designing TPS for these types of high performance applications is to establish multi-mission reusable systems with reduced weight and incr...
