I wonder if the RAF will introduce similar to the Hawk?
t least a portion of the U.S. Navy's T-45C Goshawk jet trainer fleet is in the process of being modified with new engine inlets that feature a distinctively aggressive forward sweep. The inlets are intended to help mitigate potentially dangerous compressor stalls and surges that the aircraft may experience when executing high-dynamic maneuvers.
Aviation photographer Scott Stephens (https://www.facebook.com/scottstephens111) recently took some great pictures of one of the modified T-45Cs while it was at Meridian Regional Airport in Mississippi. He was kind enough to share his pictures with us at The War Zone.
"T-45 engine surge is a critical safety concern for a single engine training aircraft with over 900 surge events documented, including over 70 surges requiring engine shutdown and restart emergency action," a section of the U.S. Navy's most recent budget proposal for the 2023 Fiscal Year (https://www.secnav.navy.mil/fmc/fmb/Pages/Fiscal-Year-2023.aspx) notes.
“The Engine Inlet Modification is being developed to improve engine performance at some edges of the envelope,” Philip Paul, then Boeing’s program manager for T-45/AV-8B Programs, said in 2015, according to a story published (http://hrana.org/news/2015/07/navy-to-modify-t-45-training-jets-for-improved-performance/) by the Association of Naval Aviation. “The T-45 performs many flight maneuvers similar to high-performance fighter jets. Student pilots learn through exposure to these extreme operational regimes, which prepares them for these conditions that are outside of regular flight operations. The Engine Inlet Mod provides additional performance margin in these conditions that can stress airframe/engine integration.”
Pictures and a lot more.
