Multiple repairs/upgrades to Navy T-10 test cell, and aircraft enclosure.
Electrical, mechanical, and structural repairs were made recently to 2 existing test facilities for the US Marines.  Repairs included new lighting systems, new compressed air system, fuel tank and delivery system repair, instrumentation system repairs, acoustical door repairs/upgrades, new inflatable seal system for primary intake doors, turning vane repairs/upgrades, new CCTV systems, new FOD screens, a new 6-ton monorail and engine hoist system, and many other general repairs.

Emergency repairs made to Marine Corp T-10 test cell augmenter.
Johnston Test Cell Group recently completed emergency repairs to a MCAS T-10 test cell located on the east coast.  The cell was inoperable due to damage incurred to the augmenter acoustical system.  Work included manufacture or custom components and their installation.

Newly designed safety rail system protects operators.
JTCG completed design, fabrication and installation of two newly designed collapsible safety rail systems for AV-8 blast pits.  The new design allows users to easily and quickly collapse / fold away the pit safety rail before and after an engine run, and can be performed even if the aircraft is already in place.

JTCG introduces it's new retrofit temperature indication system.
We recently introduced our new temperature indication system/panel that allows facility operator to monitor all thermocouple temperatures simultaneously in real time during engine testing.  The indicator panel is an enunciator-style panel where the user can quickly identify over-temperatures or engine misalignment.

JTCG completes first retrofit to Navy VSTOL hush house grating system.
Johnston Test Cell Group recently completed a retrofit to the grating system in west coast Navy VSTOL hush house used for enclosed in-frame testing of the AV-8 aircraft.  The retrofit matches the power check pad mod completed several months ago.

JTCG completes first retrofit to Navy VSTOL power check grating system.
Johnston Test Cell Group recently completed a retrofit to the grating system on a Navy VSTOL power check pad used with the AV-8 aircraft.  The retrofit is an original proprietary design which has dramatically increased the grating system and component life span by as much as 4000%.  In addition, the new design allows the local activity to conduct their own repairs with off the shelf components, thus saving critical time and money.

Door repairs and maintenance completed on eight Air Force test cells.
In late 2007, we completed repairs, and maintenance on 8 double-leaf sets of acoustical doors for the US Air Force, and Army Corp of Engineers. Work included new acoustical seals, custom door hardware manufacture, threshold work and routine maintenance.

JTCG expanding product line and capabilities.
Johnston Test Cell Group recently announced they will be expanding their product line and capabilities to include newly designed acoustical panels, doors and windows, as well as some new products designed to help reduce the cost of new facilities.  We are also offering additional repair and maintenance services, such as some mechanical, electrical, and instrumentation systems.

Off-the Shelf components available.
In an effort to help cell operators reduce down time, JTCG has introduced an "off-the-shelf" replacement program for common acoustical components used in existing facilities.  This includes components for both civil and military test cells, hush houses, blast diverters, and some testing apparatus.  Call to see if we have what you need in stock.

JTCG completes failure analysis of NAVY VSTOL power checks
JTCG was asked to perform a failure analysis of components in the Navy's VSTOL Power Check pad system.  This system has been the subject of previous investigations to determine the cause or causes of premature failures.  JTCG, working with the Navy and their engineering consultants was able to identify several causes of premature failures and able to provide useful recommendations to increase life-cycle while reducing maintenance costs.

Refurbishment for USAF incorporates design improvements
JTCG recently completed a repair and overhaul project for a USAF A-18 noise suppressor.  The facility had been out of operation for several years pending a complete refurbishment, and required replacement of 70% of the structures and 100% of the acoustical components.  During the refurbishment, several design deficiencies were discovered in the upgraded design provided by the AF that had previously gone undetected.  The most significant deficiency involved improperly designed weld connections that did not allow correct thermal expansion of various parts and materials.  JTCG re-designed the connection to allow for thermal expansion, thereby increasing the expected life cycle of these components.  JTCG also provided several upgrades in materials at no increase in price that should also improve the serviceability and extend the life of the facility.

T-10 Renovation Completes engine runs. 
Last year JTCG completed a T-10 jet engine test cell renovation for the US Navy.  The T-10 has been in service for 15 years and was in desperate need of a renovation to bring the acoustical performance back to it's original design.  Since completion, the T-10 has surpassed more than 100 hours of testing time, with no component failure.  Erection deficiencies usually manifest within the first 100 hours of test cell use.
