Do you have a problem that needs solving? The staff at SJH Projects have a history in ground breaking design in the fields of protection and security. You can be helped with your issues in a professional and impartial manner, with suggestions given on design, materials, suppliers and procedures. Studies have been performed for a variety of customers including technology reviews, market surveys and concept design to meet specific requirements.

Case Study 1

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 maritme glass, greatly increases its ballsitic performance.

Case Study 2

New Generation Mineboot

NP Aerospace, a key UK Defence company wished to add landmine protection footwear to its range of personel 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. The MB100 landmine overboots were launced at the DSEI show in London in 2005. A paper on the development programme was presented on beahlf 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 personel protection from around the world.

Case Study 3

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 workled 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.
