Abstract
In recent years, when high-resolution and low-altitude imaging of forests is needed for surveillance, inventorying or continuous monitoring, the tool of choice is an unmanned aerial system (UAS), commonly known as a drone. Especially useful are vertical take-off and landing (VTOL) systems, which can take off and land vertically, and which can provide detailed information in confined or hard-to-reach areas. However, when it comes to forest operational needs, one question is frequently asked: Do the added advantages of high-end systems justify their cost ($60,000), or do low-end systems ($6,000 plus a tablet) provide similar or acceptable output?
Abstract
Ces dernières années, lorsqu'une imagerie haute résolution et à basse altitude des forêts est nécessaire pour la surveillance, l'inventaire ou le suivi continu, l'outil de choix est un système aérien sans pilote (UAS), communément appelé drone. Les systèmes à décollage et atterrissage verticaux (VTOL), qui peuvent décoller et atterrir verticalement et fournir des informations détaillées dans des zones confinées ou difficiles d'accès, sont particulièrement utiles. Toutefois, lorsqu'il s'agit des besoins opérationnels des forêts, une question revient fréquemment : Les avantages supplémentaires des systèmes haut de gamme justifient-ils leur coût (60 000 $), ou les systèmes bas de gamme (6 000 $ plus une tablette) fournissent-ils un rendement similaire ou acceptable ?

Abstract
This study aimed to evaluate, in an accelerated manner, several aerodynamic drag reduction measures applicable to Class 8 tractor-trailer combinations. The tests were conducted according to SAE J1321 Joint TMC/SAE Fuel Consumption Test Procedure - Type II (SAE International 1986). The test results show up to 5% improvement in fuel consumption for the test vehicles equipped with boat tail devices, and up to 7% for the vehicles equipped with trailer skirts.
