Poeh... leuke vragen!
Die bak ervoor is in hoogte verstelbaar, zodat die precies voor de inlaat hangt.
Ik weet dat ze op Glenn veel getest hebben met vroege straalmotoren, o.a. of zo'n ding wel wil herstarten op hoogte.
Op deze site staan heel veel foto's met commentaar: erg leerzaam

EDIT: Gevonden!
Op bovenstaande site staat een close-up foto van dezelde motor met die bak ervoor. Het is een Westinghouse 24C en de bak ervoor is voor de-icing tests.
Even kijken of ik die foto rechtstreeks kan plaatsen (of anders linken)

NACA Researcher Measures Ice on a Turbojet Engine
C-1948-22589
11/30/1948The National Advisory Committee for Aeronautics (NACA) Lewis Flight Propulsion Laboratory conducted an extensive icing research program in the late 1940s that included studies in the Icing Research Tunnel and using specially modified aircraft. One facet of this program was the investigation of the effects of icing on turbojets. Although jet engines allowed aircraft to pass through inclement weather at high rates of speed, ice accumulation was still a concern. The NACA's B‒24M Liberator was initially reconfigured with a General Electric I‒16 engine installed in the aircraft's waist compartment with an air scoop and spray nozzles to produce the artificial icing conditions. The centrifugal engine appeared nearly impervious to the effects of icing.
Axial-flow jet engines, however, were much more susceptible to icing damage. The inlet guide vanes were particularly vulnerable, but the cowling's leading edge, the main bearing supports, and accessory housing could also ice up. If pieces of ice reached the engine's internal components, the compressor blades could be damaged. To study this phenomenon, a Westinghouse 24C turbojet, seen in this photograph, was installed under the B‒24M's right wing.
In January 1948 flight tests of the 24C in icing conditions began. Despite ice buildup into the second stage of the compressor, the engine was able to operate at takeoff speeds. The number of 24C flights was expanded to five the following winter. Lewis researchers found the engine's performance was at its worst early in the flight. Ice continually built up at the inlet before being shed. Large pieces of ice passed through the engine several times without causing structural damage. The researchers found the ice on the inlet vanes resulted in half of the engine's decreased performance. Again ice formed on the first and second stage compressors without damage.
NOG EEN EDIT: de link naar de foto werkt bij mij niet. Dan maar zo:
Ga via de link naar het kopje "1946-51"
Dan is het de foto in de meest rechtse rij, nummer 7 van boven.
