Prisoner Restraint Systems Development
SJH Projects were approached to assist in the development of some prisoner restraint equipment.
There was, and still is an issue, with legal cases against the police for injuries and in some cases deaths in custody that the claimants were attributing to chest/thorax compression injuries caused by the police during the arrest and consequential processing phases.
The aim was to look at possible solutions that secured the prisoner in such as way that their chest was protected from compression. This was of potential benefit to both prisoner and the arresting/ processing officers. In the event of any traumatic illness, compression to the chest could be removed as a factor. It is not uncommon in such arrests situations for the prisoner to be under the influence of alcohol and/or drugs of unknown origin and quality. These can cause agitation and place metabolic stresses on the prisoner outside of any arrest situation.
We looked at two scenarios for this project, one in which the prisoner would be laid out flat to restrain their legs as well as arms and the other was for a walking prisoner to be transported in the rear seat of standard police car or van. Full Story
Explosives Laboratory for Foreign Government
SJH Projects successfully led and produced the technical proposal for a turnkey explosive laboratory for a foreign national Ministry of Defence. This service was provided on behalf of a UK company hoping to become the prime contractor. A site visit and meetings with the senior commanders set the scene and established the starting point, current skills and infrastructure.
Through an extensive network, appropriate specialist partners were identified and brought into the team. The detailed proposal included the new buildings and services, all the internal specialist laboratory equipment and access to very high level training programmes for potential staff both in country and at leading UK establishments with Government support.
As might be expected for such a programme the paperwork was considerable and the bureaucracy top notch but perseverance paid off and the contract was awarded in June of 2016.
Counter Piracy Technology
The surge in piracy has created a need to improve the protection of commercial vessels. SJH Projects has worked with strategic partners Idarat Maritime to design, assess and implement a range of technologies and procedures that provide viable protection and value for money. This is an ongoing programme providing stream of
enhancements to an ever evolving situation.
One example of this programme was the development and testing of the 'Water Dragon C2' clear film that when used as a backing to maritime glass,
greatly increases its ballistic performance.
New Generation Mineboot
NP Aerospace, a key UK Defence company wished to add landmine protection footwear to its range of personnel protection equipment. Although experienced in the production of composite armour systems for both vehicles and personnel, they did not have specific experience in this niche sector. NP Aerospace and SJH Projects worked together to develop a strap on overboot that provides protection from many
of the common anti-personnel landmines that litter the worlds previous (and current)war zones.
The test programme was conducted in line with the latest NATO protocols and used surrogate test limbs that were specifically designed for just such a purpose.
TheMB100 landmine overboots were launched at the DSEI show in London in 2005. A paper on the development programme was presented on behalf of NP Aerospace by Steve Holland of SJH Projects at the Personal Armour Systems Symposium (PASS) at the Royal Armouries in Leeds in September 2006. This symposium pulls together the leading specialists in personnel protection from around the world.
Aircraft Engine Bay Armour
It is an intrinsic risk with jet engines that one of the fan blades might detach whilst the engine is spinning at very high speeds. Technology built into the engine casing is usually enough to decelerate and contain such a fan blade so that is does not leave the engine altogether. If it did it could pose a threat to the wing, a neighbouring engine or even the passenger compartment.
Some engines however are mounted within the wing of the aircraft and this existing technology is not sufficient to prevent the detached fan blade from impacting with the walls of the engine bay. SJH Projects worked with AML UK Ltd to produce and test a composite armour engine bay lining for just such an occasion. With a very limited space envelope and tight weight restrictions, a variety of potential configurations were tested. The customer was then able to select from the successful candidates which option was the most suitable for use over the full life span of the aircraft.
