Arc jet Test-Article Surface Recession Rate Monitor

Phase 1 SBIR

Agency: Air Force
Topic: AF141-228
Budget: 07/08/14 - 03/31/15
PI: Dr. Jim Crafton

ABSTRACT: Quantitative ablation recession rate measurements of heat shield surfaces are essential for evaluating the performance of heat shield materials. Currently, these measurements are limited to two-dimensional images that focus on the nose tip regression rate. For wedge testing, recession rate is determined by comparing pre- and post-test ...

Fast Responding Pressure-Sensitive Paint for Large-Scale Wind Tunnel Testing

Phase 2 SBIR

Agency: National Aeronautics and Space Administration
Topic: 12-2-A3.07
Budget: 01/01/14 - 12/31/14
PI: Dr. Jim Crafton

The proposed work focuses on implementing fast-response pressure-sensitive paint for measurements of unsteady pressure in rotorcraft applications. Significant rotorcraft problems such as dynamic stall, rotor blade loads in forward flight, and blade-vortex interaction all have significant unsteady pressure oscillations that must be resolved in or...

Hypersonic Propulsion: Improvements in Controls and Instrumentation

Phase 2 SBIR

Agency: Air Force
Topic: AF112-182
Budget: 02/14/13 - 05/08/15
PI: Dr. Jim Crafton

ABSTRACT: Among the technical challenges associated with current Air Force scramjet technology development is coupling between the combustor and isolator that leads to isolator unstart. Performance is currently restricted because the engine is not actively controlled. While simple passive techniques such as cavities for shock capture exist, they...

Aircraft Tire Contact Patch Force and Shear Sensor

Phase 2 SBIR

Agency: Air Force
Topic: AF093-210
Budget: 05/17/12 - 05/17/14
PI: Dr. Jim Crafton

ABSTRACT: Military aircraft tires must handle extreme loads during landing, take-off and taxi. New designs must be evaluated to determine if they meet mission capability requirements. A key evaluation area is the distribution of normal and shear forces in the tire contact patch. These data are critical for understanding tire performance, tire/la...

Fiber-Coupled Pulsed and High-Intensity Ultraviolet Optical Measurements for Propulsion Systems

Phase 2 SBIR

Agency: Air Force
Topic: AF103-199
Budget: 04/20/12 - 08/20/14
PI: Anil Patnaik

ABSTRACT: Based on the success of the Phase-I effort, the objective of the proposed Phase-II research effort will be to develop and deliver a system of fiber-coupled, high-speed UV-LIF- and PLIF-based sensor. During this effort we will 1) quantitatively measure spatially resolved 2D temperature in laboratory flames, 2) develop technology for si...

Simultaneous Skin Friction and Pressure Sensitive Paint

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 11-1-A4.01
Budget: 01/01/12 - 12/31/12
PI: Dr. Jim Crafton

Currently, the contribution of skin friction to the total drag of a wind tunnel model is estimated by comparing measurements of the total drag to the integrated pressure drag. While this yields an estimate for the average skin friction, the distribution of the skin friction cannot be determined from such measurements. The distribution of skin fr...

Skin Friction and Pressure Measurements in Supersonic Inlets

Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 11-1-A2.10
Budget: 01/01/12 - 12/31/12
PI: Dr. Jim Crafton

Supersonic propulsion systems include internal ducts, and therefore, the flow often includes shock waves, shear layers, vortices, and separated flows. Passive flow control devices such as micro-vortex generators and micro-ramps have been proposed to improve vehicle performance. The ability to measure surface quantities such as skin friction and ...
