1. Temperature Control Systems
We are developing cooling and heating military systems with various features and levels that can meet the cooling needs of our customers in the most comprehensive way. Three main examples of these systems can be given. These are Liquid-Cooled Chassis, Cold Plates, Heat Exchanger.
a) Liquid-Cooled Chasis
Liquid-cooled chassis, also known as Liquid Flow-Through (LFT) electronic chassis, are card-level heat sink technologies. The chassis consists of aluminum cold plates with corrugated aluminum fins vacuum brazed to the sidewalls. Heat is transported from the plate to the sidewalls to the liquid by conduction. The inner fin creates an additional surface area for heat transfer and creates turbulence in the fluid to optimize performance.
b) Cold Plates
Cold plates are the basis of the liquid-cooled chassis and are used to cool phased array radars, electronic countermeasure compartments, environmental control units, and more. Cold plate technologies include tubular, straight tube, and performance fin. The vacuum brazed performance wing is the cold plate technology most commonly found in aircraft. Performance fin cold plates consist of two metallurgically bonded plates with an inner fin, the most common of which is vacuum brazed.
c) Heat Exchanger
Heat exchangers are generally used to cool hydraulic oil, engine oil, and EGW with ram air inlet system or with a fan. Ram air can also be replaced with an ethylene glycol solution or PAO as a heat sink. For example, PAO is sometimes used in intercooler applications to cool gaseous nitrogen (GN2) to inert fuel tanks to reduce fire hazards.
2. Fluid Control Systems
Managing fluid flow and inflow is a critical part of optimizing and maintaining complex systems. We develop fluid control systems with various features and levels that can meet the fluid control needs of our customers in the most comprehensive way. By using a variety of technologies to control fluids such as air and fluid, we help products last longer in harsh environments.
3. Equipment R&D
We develop the necessary equipment and subsystems according to the system requirements of our customers. There are four main examples of these systems. These are Environmental Control Systems, Discharge Air System (Pneumatic System), Air Leak Detection Systems, Air Conditioning Systems.
a) Environmental Control Systems
Environmental Control Systems control the temperature, pressure, and airflow to the aircraft's pressure vessel, which includes the cockpit (flight deck), cabin, and interior compartments.
b) The Bleed Air System
The Discharge Air System, also known as the Pneumatic System, provides the air needed by the lower consumers while adjusting the pressure and temperature of the air coming from the engines to 45 PSIG and 200oC, respectively. The system also selects the engine port from which to bleed.
c) The Bleed Air Leak Detection
Leaking air is a fire risk, eg. max. The allowable surface temperature to prevent self-ignition of the fuel is 204oC per FAA AC 25.981-C. Leakage is also a risk for aluminum and especially composite primary structures. Leak detection is required via thermal switches (zonal sensors) or continuous elements routed through air vents.
d) The Air Conditioning System
The Air Conditioning System (ACS) conditions the fresh air from the Extract Air System. It also provides the desired mass flow to the cockpit and cabin areas. Conditioning means regulating temperature and removing moisture. The system makes it possible to recirculate some of the cabin air.
