​​​​​​​​​​​DEFENCE CONSULTANTS


Our defence consultants provides defence systems design and simulation services across air, naval and land systems. In addition to the defence systems design services that we offer, we also provide third-party independent assessment of defence systems. Since Jimmy Lea P/L is not affiliated with any private or public entity, our reports are known to the clients as impartial, unbiased and without any prejudice. ​The defence projects that we have contributed to and help to deliver were:


Our defence consultants performed the fluid structure interaction (FSI) analysis to study of the interactions between projectiles and various protective materials. We performed CFD modelling and simulation of JSF Fighter Jet 50 mm projectile to determine its drag coefficient and provided recommendations to the projectile’s designers to improve its geometry and reduce the drag coefficient. We also performed CFD simulation of unmanned aerial vehicle (UAV) to determine its drag coefficient, provides recommendation and improve the geometry to reduce the drag coefficient. We conducted multiphase CFD modelling and simulation study to characterise a marine vessel-crew boat with respect to its hull resistance, drag coefficient and to predict its maximum speed and then we provided guidance to the naval architecture team to optimise the boat hull form.

Our defence systems design consultants mentored the multidisciplinary engineering team to develop and/or improve projectiles, rocket propellants, high explosives, plastic explosives, handcuffs, Mark 80 and Mark 82 aerial bombs. We mentored the defence engineers on subject related to increasing the reliability of plants producing high explosives and delivered specialised engineering workshops, SQC trainings and administered tests to multidisciplinary operations engineers involved in the manufacturing of rocket propellants, high explosives and aerial bombs.


​​As defence systems consultants, we provided engineering consulting services and blast effects analysis (BEA) to multidisciplinary engineers involved in the design and manufacturing of armoured vehicle. Mentored multidisciplinary engineering team to improve the design of the Bushmaster armoured vehicle. We performed detailed quantity-distant analysis on the effect of overpressure of shock and blast waves against the armoured vehicle. We conducted blast waves simulations to determine the impact of detonations from a buried IEDs against the belly of the armoured vehicle and evaluated the damage sustained by the armoured vehicle. We also performed CFD thermal analysis of armoured vehicle to improve engine thermal management system. As part of the simulation study, we performed modelling and simulation validation trial on the armour plate. We also conducted study to ensure the design of the engine grill was optimised to allow maximum air to enter the engine compartment whilst minimising the chances of projectiles hitting the engine.
