Application Of Acoustics in Thermal Insulation and Blast Deflectors

Irregular forms, such as pipes and valves, necessitate a one-of-a-kind insulation solution in OEM equipment. A blanket or cover with thermal insulation to fit your needs and provides a tailored approach for OEM exhaust applications requiring long-lasting high-temperature heat insulation. Temperature-resistant products like silica fibers, high-temperature fiberglass, calcium silicate fiber, silicone, and PTFE coated fiberglass cloth, aluminized fabrics, and SS mesh are used to make thermal insulation blankets. Durability, thermal efficiency, and custom fit are all built into these sewn or molded thermal insulation blankets and covers for hot and cold applications. Aerospace, Agriculture, Marine, Oil & Gas, and Power Generation are only a handful of the sectors that use thermal insulation blankets and covers.

 Advantages of Thermal Insulation Blankets:

• Excellent heat preservation and safety of surrounding parts

• Attractive and simple to mount and uninstall

• Per application is optimized for efficiency and expense

• Consistent consistency and blanket performance from order to order

Thermal insulation blankets are made of heat-tolerant fabrics for devices with higher temperatures (up to around 1800oF), such as exhaust pipes and heaters. These may be engineered and manufactured for permanent or serviceable use on vehicles, vans, power turbines, heaters, and other high-volume manufacturing equipment. To prevent fiber irritation on the production line, many of our projects completely enclose the insulation sheet.

We may mold thermoplastic polyethylene foam insulation to “fit like a glove” to have fast and simple installation and removal for chilled water pipes and low to medium temperature applications (up to around 200oF). These devices also substitute the time-consuming and unreliable process of wrapping pipes and valves. This approach is ideal for insulating a large amount of repeatable hardware.

Thermal Insulation Blankets & Covers are seen in a variety of situations.

  • Condensation safety on cooling water lines, pumps, and water heat exchangers 
  • Heat preservation for diesel engine regeneration cycles 
  • Enclosed heat protection from exhaust systems in vehicles, vans, coaches, and generators
  • Gas and steam tubing are thermally and acoustically insulated.

The thermal insulation blanket prevents surrounding environments and materials from excessive heat damage in certain applications. They preserves the heat required for optimal device operation in other cases.

Introduction To Jet Blast Deflectors

A blast fence, also known as a jet blast deflector, is a device that deflects the jet blasts. The device that guides high-energy emissions from a jet engine to a safe location protects you from harm and injury. The structure must be able to withstand fire, high-speed air streams, and dust and debris carried by turbulent air. Jet blast may be hazardous to humans, machinery, cars, and other aircraft if there is no deflector in place.

Types Of  Jet Blast Deflectors

Jet blast deflectors vary in size from simple concrete, aluminum, or fiberglass fences to heavy panels with hydraulic arms that are lifted and lowered, and continuously cooled. Prop wash from helicopters and fixed-wing aircraft may be mitigated with blast deflectors. Plane blast deflectors can be coupled with sound-deadening walls at airports and jet engine repair centers to provide a ground run-up enclosure in which a jet aircraft engine can be measured at maximum thrust efficiently and silently.

Importance Of Jet Blast Deflectors?

The exhaust from a high-powered jet engine will trigger injuries and destruction. Trees have been reported to be uprooted, windows shattered, cars and vehicles overturned, houses flattened, and people injured by the jet explosion. Jet exhaust has blown around and destroyed other aircraft in the jet blast, particularly lightweight aircraft. At lengths of more than 200 feet, hurricane-force air streams with speeds of up to 100 knots (190 km/h; 120 mph) have been estimated behind the largest jet-powered aircraft (60 m). The thrust generated by the two General Electric GE90 engines on a Boeing 777 is about 200,000 pounds-force (900,000 N), which is enough to destroy people. Jet blast deflectors steer the air stream in a safe path, usually upward, to avoid these issues.

How Aircraft Carriers’ Jet Blast Deflectors Work?

Jet blast deflectors (JBD) are installed at the back of aircraft catapults on aircraft carriers to shield other aircraft from damage caused by exhaust blasts. Hydraulic cylinders or linear actuators lift and drop the jet blast deflectors, which are constructed of heavy-duty steel. Until the plane to be fired rolls over it on its way to the catapult, the jet blast deflector is flat with the flight deck and acts as a portion of it. The strong panel is lifted into place to redirect the hot jet blast until the aircraft has cleared the deflector. Another aircraft may be pulled into place behind the deflector as soon as it is lifted, allowing flight deck staff to complete final readiness tasks without being exposed to heavy, and violent exhaust gases. As jet-powered aircraft became more common in navies, such systems were deployed on aircraft carriers in the late 1940s and early 1950s
