Unmanned Autonomous Helicopter

Northrop Grumman Corp.
West Falls Church, VA

All Navy aircraft must go through electromagnetic interference testing to ensure that they can operate safely in the ship environment. In preparation for ship-board flights, the Northrop Grumman Corporation’s MQ-8C Fire Scout will be tested for its ability to operate safely in the intense electromagnetic environment aboard U.S. Navy ships. The MQ-8C Fire Scout uses specially designed Faraday cages to protect the aircraft’s sensitive equipment from signal interference.

Automatic-Alignment Fiber Optic Coupling System for Optimal Signal Transmission

Using the current method of characterizing waveguides manufactured for research in optical communications, it can take up to 8 hours to characterize the waveguides on a single silicon wafer. Using the automatic computer automation system developed, the characterization process has been reduced to less than an hour. After the silicon wafer containing the waveguides is manufactured, the waveguides must be evaluated to determine the optical characteristics of the various waveguides on the silicon wafer.

Detecting Maritime Radiological/Nuclear Threats with Hybrid Imaging

The SuperMISTI detection system is a hybrid detection, identification, and imaging system for sources of gamma-ray radiation at stand-off distances. The system is based on the Mobile Imaging and Spectroscopic Threat Identification (MISTI) system designed for the Department of Homeland Security. The SuperMISTI system uses the high-resolution spectra of high-purity germanium (HPGe) detectors to detect and identify gamma-ray sources as well as coded aperture technology, and lower-cost NaI detectors to image and localize the detected sources. The system utilizes a modular design to allow the detection/identification and the imaging/ localization portions to be used separately or together, depending on the situation.

Testing Particle Counters for Detection of Fuel Contamination

Fuel quality assurance is accomplished by conducting periodic fuel sampling for the condition monitoring of aviation fuel by detecting, measuring, and reporting the levels of contaminants in the fuel. Current methods have several drawbacks including operator subjectivity, lack of detailed analysis, limitations in providing reliable data, and the turnaround time needed to get the test results.

Unmanned Aircraft Must Rise Above Barriers for Commercial Applications

Historically, the unmanned aircraft system (UAS) market has been dominated by military applications from surveillance to active engagement. In the near term, the market’s military focus is expected to continue. However, with projected growth from around $6 billion today to nearly $12 billion in 2023 (according to the Teal Group), large-scale commercial adaptation is not only possible, but likely.
