Jet blast deflectors
Jet blast deflectors are used where aircraft engine exhaust can affect apron operations, taxiways, service roads, parked equipment, buildings, or nearby public areas. They are designed to redirect or reduce the impact of blast flow in locations where operational safety and usable space must be maintained.
Jet blast protection design must account for aircraft type, thrust setting, protected areas, and airport operating conditions, as blast exposure can quickly become a safety issue if not properly managed.
Key design considrations
- aircraft mix and engine height
- power setting and exhaust velocity
- area requiring protection
- available space and geometry limits
- height restrictions
- operational safety requirements
- noise considerations
- technical validation and project-specific constraints
Typical Applications
Jet blast deflectors are typically used in airport areas where aircraft exhaust may affect operations, infrastructure, or safety-sensitive zones. Depending on layout and operating conditions, they can be applied to protect both airside and adjacent operational areas.
- taxiways
- apron and ramp areas
- engine run-up areas
- maintenance and test locations
- roads and parking areas
- buildings, equipment, and personnel protection
- areas exposed to breakaway or full-power blast conditions
Common Jet Blast Deflector Types
Curved Jet Blast Deflector
Curved jet blast deflectors are often used where aerodynamic efficiency and controlled redirection of exhaust flow are important. They are commonly applied in airport environments where roads, buildings, parking areas, or airside infrastructure need to be protected.
Vertical and Mesh Deflectors
Vertical and mesh-based concepts may be used where different geometric, airflow, visibility, or site-specific constraints apply. These solutions can provide practical protection where a curved arrangement is not the best fit.
Portable and Temporary
Portable or temporary jet blast deflectors can be appropriate where flexibility, phased works, or temporary operational arrangements are required. These concepts can help maintain protection in changing airport environments.
Fiberglass Defelctor
NAVAID compatible deflectors tested and approved by the FAA
Fiberglass jet blast deflectors can be used where corrosion resistance, reduced maintenance requirements, or project-specific operational considerations make composite solutions advantageous. Depending on the application, fiberglass configurations may offer a practical alternative to conventional metallic arrangements while still providing effective jet blast protection for surrounding airport areas and infrastructure.
Deflectors for Run-Up and Multi-Heading Applications
In some airport and maintenance applications, jet blast protection may need to accommodate engine run-up positions or varying wind conditions. Multi-sided or adapted deflector configurations can be used where multiple orientations must be considered.
Engineering & Technical Support
APS Germany supports jet blast protection projects from early evaluation through implementation.
Depending on the requirement, this can include blast analyses, project drawings, project-specific renderings, configuration recommendations, regulatory guidance, inspection, maintenance input, and budgetary pricing support.
