The Model 133-4.62 Advanced Technology Tactical Transport (ATTT) proof-of-concept demonstrator is a 62% scaled version of an airplane designed to challenging STOL and long range requirements. The prototype first flew on December 29, 1987.

| Ray Cox, rc2154(@)hotmail.com, 02.10.2007 As this aircraft clearly has a horizontal rear stabilizer, I suspect the stub wing at the front provides lift, making the ATTT a Tandem-Wing aircraft. | | Simon Gunson, simmon_gunson(@)paradise.net.nz, 25.02.2007 I notice the canard has anhedral and the main wing dihedral. I take it therefore that this is because there is a real risk of the front wing interfering with or blocking airflow to the main wing ? Also when Mt Cook Airlines in the 1980s used BN Islanders as skiplanes in New Zealand they found the attachment of undercarriage to a very rigid wing structure caused wing spar cracks. Is this aircraft going to be tested/evaluated for this type of stress ? -Simon Gunson |
