  1. Thank you all for taking the time to provide your input and insights. All of your explanations helped me understand the charts a lot better. Thanks for a good discussion!
  2. Eric, thanks for taking the time to respond to my questions. Can you explain more what you mean by "It won't be the same curve, because the drag is factored by the speed to get power, but the shape will be similar - see that they show that max endurance isn't at the apex on the drag chart, but it is on the power chart." Why are the curves not the same (Why are the apexes different? Why isnt power directly related to total drag? As I increase in airspeed the power required will decrease past TFE and ETL because induced drag decreases. As I continue to increase airspeed, eventually parasite drag will drastically increase requiring more power. I recognize that I am probably oversimplifying things but I am trying to figure out what factors make the apexes different.
  3. I am looking for an explanation of Drag Charts and Cruise Charts (aka Power Curves). I am an Army Aviator and the majority of my questions are coming from TC 3-04.4: Aerodynamics of Flight (Pgs 1-27, 1-28). 1-78. Maximum range airspeed is an airspeed that should allow the helicopter to fly the furthest distance. It is determined by flying where airspeed intersects the lowest amount of total drag (point E on figure 1-41, page 1-27). However, due to flight testing and aircraft performance, cruise charts are used to determine torque and fuel flows required to maintain that airspeed. Because cruise charts are not drag charts, it can be noted the lowest point of a drag chart does not necessarily match the lowest point of the power required curve in a cruise chart. 1-79. Maximum Endurance airspeed is an airspeed that allows the helicopter to remain flying the most amount of time. It can be found on the power required curve of the cruise chart where power required is at its lowest and not necessarily where total drag is lowest on the drag chart. Questions: -Why isnt Max Endurance ALWAYS the lowest total drag? What factors make it not the least amount of drag? -What factor(s) make drag charts different from cruise charts/power curves?
  4. Thank you all for sharing your experience and advice!
  5. Hi everyone, I am looking for some advice. I am a civilian and I was accepted into WOFT. I leave in January for BCT. My fiancee and I are trying to decide when to get married. We would like to have our wedding right after WOCS. Is that practical? Should we consider getting legally married before BCT and having the wedding after WOCS during the 10 day moving period? From what I have read on the forums and from researching online, the biggest benefit with getting married before BCT is moving into married housing after WOCS, PCS move, BAH pay, separation pay, and medical insurance. Does anyone have any other perspectives, experience, or advice? Thanks!
