Universal Ground Run Blast Deflector
A Universal Ground Run blast deflector (UGRBD) is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury.
A Universal Ground Run blast deflector (UGRBD) is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury. The structure must be strong enough to withstand heat and high-speed air streams as well as dust and debris carried by the turbulent air.
Universal Ground Run Blast Deflector can be combined with sound-deadening walls to form a ground run-up enclosure within which a jet aircraft engine can safely and more quietly be tested at full thrust Facilities equipped with Universal Ground Run Blast Deflector may be used for the objects featuring the following characteristics:
| Characteristic | Specification |

| Number of engines | 1 or 2 engines |
| Maximum height from the ground to the engine axis | 2200 mm |
| Maximum spacing between the engines as viewed in the plan view | 2600 mm |
| Distance between the attachment fittings on the landing gear | 1200 to 4400 mm |
| Height of the attachment fitting from the ground to its location on the landing gear strut | Up to 1000 mm |
| Distance from the main landing gear to the exhaust nozzle exit of the engines | 4200 to 7700 mm |
| Tilt angle of the engines relative to the horizon | 1 to 3.5° |
