Verification of the Guidance, Navigation and Control (GN&C) algorithms and software utilized onboard spacecraft is of paramount importance to ensure resilient, correct operation after launch. Rather than wait until the GN&C software has been deployed to perform on-orbit verification, offline verification integrated into the design process will improve mission performance, significantly reduce the ...

Radio frequency communications and sensors are everywhere in both personal and military life. RF fields are also used in some medical therapies. However, little is known about the medical effects that result from the routine exposure of tissue to RF fields. To understand such effects, new instrumentation is needed that can quantify the RF radiation amplitude with spatial resolution comparable to t ...

This proposed project combines advanced thin film materials engineering technology with state of the art photonic integrated circuit device concepts to develop next generation integrated electro-optic modulator devices. The proposed high speed thin film electro-optic modulator technology fills a critical need for compact, low voltage, and high analog bandwidth linear electro-optic modulators in si ...

The Department of Defense relies on a worldwide network of radar and optical sites to maintain Space Situational Awareness.Although careful consideration during site selection process solves some of this mission's challenges, optical sensor imaging of objects at significant ranges is always hampered by many other factors, such as limited-aperture optics and atmospheric turbulence.There remains, ho ...

The development and implementation of new damage morphology models for concrete materials is critical to understanding their dynamic behavior during severe shock loading environments.Current constitutive models of conventional strength concretes do not accurately represent the behavioral characteristics of new ultra-high strength concretes because of differences in damage mechanisms during failure ...

The advancement of flight vehicles, including hypersonic vehicles, requires increased performance from RF shielding material capable of withstanding the dynamic and thermal loads of the vehicle while maintaining RF performance.Efforts conducted as a response to this program will develop and characterize material for use as radomes and conformal apertures of flight vehicles and other extreme enviro ...

This Phase-II STTR research effort is designed to forward the engineering investigation of the dynamics and control of turbulent combustion in high-pressure combustion systems by developing a set of game-changing nonlinear analysis tools that can significantly improve the post-processing speed and intelligent data mining of large numerical or experimental data sets. Moreover, a system based on non ...

J.T. McGraw and Associates,LLC,in collaboration with Purdue University, propose to demonstrate and test deployment of prototype COTS-derived optical SSA sensors designed to rapidly reconstitute and enhance global surveillance of GEO and near-GEO space.JTMA's advanced designs, techniques and algorithms allow small telescopes to achieve sensitivities very near those of larger traditional systems.Whe ...

Thermoelastic structures pose a critical challenge to designers due to the inherent design dependence of thermal loading on structural thickness. This is further exacerbated by structural nonlinearity due to in-plane, and more importantly, the out-of-plane bending deformation that further increases the effective loading on the structure. During Phase I of this project, we have added significant ne ...

The overall goal of the proposed research program is to develop a ruggedized imaging system capable of visualization and analysis of the particle field and product gases in a multiphase blast. This will be accomplished by combining kHz-MHz-rate burst-mode laser technology with tomographic particle field velocimetry (PFV) and new nonlinear particle tracking methods to resolve dense particle fields. ...
