Maintenance Training Devices

Chinook Training Device Program

LSI designs, develops, and delivers high fidelity Chinook helicopter training environments for the Program Management Office (PMO), Cargo Helicopters.  LSI uses Crash Damaged Aircraft (CDA) or CAT-B aircraft fuselages combined with simulated components to support all mechanical and electrical system tasks in a simulated environment increasing training capabilities and improving training effectiveness.  Our solutions require no original equipment manufacturer (OEM) software or components to generate the displays and signals needed to support completion of IETM tasks and rendering appropriate results.  Everything is simulated but transparent to the student.  This solution was recognized by US Army representatives in the 2011 US Army Aviation Logistics School (USAALS) Army Aviation Magazine to have “become a model of success for USAALS, PEO Aviation, and industry collaboration.”

LSI delivered ten CHMT10 (15U10), four CHMT30 (15U30), and four CHMT-EV (15F) training devices leveraging the engineering design and lessons learned from CHMT 10 devices to produce the CHMT 30 and subsequently the CHMT EV devices.  This leveraging provided the ability to adjust training models to allow the EV device to be used to train 15U tasks if desired.  These training devices are used to support initial and skill maintenance instruction for Helicopter Repairer and Aircraft Electrician Maintenance personnel.  These devices also support remove, install, and fault isolation scenarios for aircraft systems and subsystems.

Each CHMT training device consists of a Hardware Training Device (HTD) an Instructor Operator Station (IOS), and an Aviation Ground Power Unit (AGPU), and the capability to be synchronized with a Virtual Interactive Environment (VIE) training device.  This platform makes available two types of training tasks -- instructor initiated actions that require no computer or simulation hardware interaction and instructor initiated system and component faults that are induced via the IOS software application.

The CHMT-10 Level Device provides training for 15U10 tasks, including component identification, system familiarization, 6 service tasks, 51 remove and install tasks, and 31 fault isolation procedures (FIPS).

The CHMT-30 Level Device provides training for 15U30 tasks, includes all 15U10 level tasks with the addition of 13 maintenance operational checks (MOCs) and 23 FIPs.

The CHMT-EV Level Device provides training for 15F10/30 tasks, includes all the functionality of the 30-level trainer plus the ability to do 30 more MOCS and an additional 118 FIPS.

Chinook Rotor Head Part Task Trainer (CRPTT)

LSI delivered two CRPTT training devices to support the training environment for development of maintenance skills and knowledge for CH-47 maintainers.  The trainer serves as the training media for instructors to strengthen maintenance personnel in skills and knowledge of system familiarization, component identification, maintenance procedures, and removal and installation procedures.  The trainer simulates production aircraft systems to the extent required to accomplish the maintenance tasks for the rotor head system.  These systems provide realistic training for maintenance procedures.

Chinook Cockpit Part Task Trainer (CCPTT)

LSI delivered two CCPTT training devices to support the training environment for development of maintenance skills and knowledge for CH-47 maintainers.  The CCPTT is representative of aircraft flight control systems configuration of the CH-47 and is populated with components that meet the physical and functional fidelities of the aircraft.  The trainer serves as the training media for instructors to strengthen maintenance personnel skills and knowledge of systems, component identification, maintenance procedures, and removal and installation procedures.  The trainer simulates production aircraft systems to the extent required to accomplish the maintenance tasks for the selected systems.  These systems provide realistic training for maintenance procedures.

Black Hawk Maintenance Trainer (BHMT)

The UH-60M Black Hawk Maintenance Trainer (BHMT) is built from retired Category B, crash damaged, or purchased airframe and is used for the development of maintenance skills for U.S. Army Military Occupational Specialty (MOS) 15T10 and 15T30 level personnel.  It is used to train system familiarization, component identification, servicing tasks and inspections, Maintenance Operational Checks (MOCs), Fault Isolation Procedures, and Remove and Install (R/I) tasks in support of UH-60M Aviation Unit Level Maintenance (AVUM).  The BHMT-M provides realistic, safe, high fidelity training for ground maintenance operations and procedures.  It is the primary training media to strengthen maintenance personnel skills and knowledge in:

  • Maintenance task related skills and knowledge
  • Maintenance practices and repair procedures
  • Use of common and special tools, and test equipment
  • Advanced skills development

The BHMT-M trainer is ruggedized for the training environment to provide high life cycle task performance at low cost and provides for isolation of task environments for system familiarization to support the 15T MOS at the 10 and 30 levels.

The BHMT-M consists of a Hardware Training Device (HTD) with a Mobile Power Supply Unit (MPSU), an Instructor Operator’s Station (IOS), Trainer System Software, IOS Software, and an Air Conditioning Unit within the Computer Equipment Rack.  The HTD is representative of a UH-60M aircraft, incorporating simulated systems, requiring electrical and hydraulic power from the MPSU.  The BHMT-M training system retains the original look and characteristics of the UH-60M helicopter, with the addition of maintenance platforms to facilitate training.  The forward L/H and R/H sides of the work platforms allow for rotor blade installation and transmission, engine, and APU R/I, and other tasks requiring safe access to the top of the trainer.  The BHMT-M comes with UH-60M composite modeled stubby rotor blades that are nine and a half feet long and replicate the shape, twist, and anhedral tip of an actual UH-60M rotor blade.  A tail rotor stand is provided to allow R/I tasks on the tail rotor and tail rotor gear box.  The work platforms come with gates that have safety sensors to prevent the rotor blades from turning if a gate is opened.  A sensor is provided to prevent rotation of the rotor system if the tail rotor stand is in a position to interfere with the tail rotor blades.  An additional sensor prevents the system from rotating if the railings are not in the down position.

Physical and functional fidelity requirements for all components are defined in a customer-provided Fidelity Matrix.  The IOS enables the instructor to monitor and control the training scenario, observe and evaluate student performance, and check system status.  The IOS provides two modes, one for training and the other for maintenance.

LSI, Inc. designs, develops, manufactures and delivers high fidelity Black Hawk helicopter training devices for the Utility Helicopter Project Office (UHPO) for use at the U.S. Army Aviation training facilities at Ft. Eustis, VA and Ft. Indiantown Gap, PA. Five of these devices have been delivered and five more are in production. LSI has delivered one trainer for the Taiwan Army under a foreign military sales (FMS) case.
