A new cable network, utilizing a grid-like pendant cables will increase individual pendant cable life and reduce engine wear. upon completion of a successful design study and associated testing, the grid cable system would enhance reliability and dependability for the existing mk 7 mod 3 system… More

Develop a sensorless control scheme, including hardware and algorithms that can effectively and accurately control a long linear motor. Eliminate the need for sensors to control operation, since sensors are the most failure prone components in thesystem.This would have direct and immediate benefits… More

The objective of Phase II is to take the control algorithm developed in Phase I and actually develop the software necessary to implement the control algorithm and demonstrate the sensorless control system on the Northrop Grumman EMALS Team Subscale Integration Testbed (SSIT) which is a scale model… More

Demonstrate the feasibility for a compact, lightweight, high power density shipboard Advanced Variable Speed Drive. The drive must interface to the Integrated Condition Assessment System (ICAS)to more efficiently and automatically run shipboard induction motor applications.

Develop the electronics and controls for a low-distortion, quiet, and reliable output three-phase 0 to 20 kiloHertz power converter with current 0 to 50 kiloAmperes. The output frequency and current must be able to vary from minimum to maximum within a 300 millisecond time period. NDI offers the… More

Future Naval applications will require large pulses of electrical power for short time duration. NDI and it's university partner will conduct an investigation to determine the feasibility of developing a compact pulse generator to meet the Navy's need and include an assessment of cost and… More

Develop a sensor and display that indirectly indicates if JBD panels are fouled, and displats aircraft weight info to pilot and others. The goal is to eliminate the JBD Operator and the Weight Board Operator from hazardous positions on the flight deck.

Develop an affordable, lightweight, low volume,power dense, linear motion system that can be universally applied to service a variety of shipboard operations that require a broad range of force and stroke.

Develop and test a subscale prototype Phase Switch Inverter to demonstrate that it can deliver a pulse of 0 to 10 kApk, sweep from 0 to 10 kHz within 5 msec. and that by simply paralleling additional IGBT's can provide 50 kApk. This will require the detail design, fabrication, and demonstration of a… More

Produce protype and successfully demonstrate the key technology areas identified in Phase 1,thereby significantly reducing the technical risk for successful development of the concept. Complete a thorough design of the concept, including electromagnetic, electrical, mechanical, and thermal analysis… More

Phase I offered a simple, effective means of providing electronic communication between the weight board operator, aircraft pilot, the Catapult Officer and the Central Charging Panel (CCP) operator.Phase II refines development and moves onto the testing of a full scale prototype system. Through… More

Develop a flexible, compact cable or conductor capable of handling the repetitive, high magnitude, high transient, pulsed loading and flexing service required by a Naval Electromagnetic Railgun (EMRG).

The United States Navy is continuing to expand the utilization of linear electric power in a variety of military applications. Linear synchronous or induction motors can be readily modularized to accommodate the size, weight, power and energy density requirements of a wide range of shipboard… More

With the Navy proceeding on its goal of an all-electric ship, innovative R & D methodology is needed to model and validate high rate, intermittent energy storage and control architectures that can rapidly accept high intermittent currents to load-level prime movers during the pulsed-power duty… More
