7.25 To obtain maximum range for a thrust-producing aircraft, as fuel is burned _______________. But even in high-performance aircraft capable of steep climb angles where this is no longer the case, it can be geometrically shown that the steepest climb angle also occurs when the ratio of vertical speed to airspeed is maximized. We might start with cruise since a certain minimum range is often a design objective. and we can plot T/W versus W/S just as we did in the cruise case, this time specifying a desired rate of climb along with the flight speed and other parameters. On the other hand, the climb curve should be plotted for optimum conditions; i.e., maximum rate of climb (minimum power required conditions for a prop aircraft) since that is the design target in climb. 2.23 Calculate the pressure altitude for an aircraft at an airport with a field elevation of 2,350 feet MSL when the current altimeter setting is 30.40".

Is email scraping still a thing for spammers. It only takes a minute to sign up. 7.22 The value of (L/D)max changes when the gear and flaps are lowered. One finds the desired takeoff distance in feet on the vertical axis and projects over to the plot for the type of aircraft desired, then drops a vertical line to the TOP axis to find a value for that term. And this can be written [W/S] = Vstall2CLmax, On the plot above this would be a vertical line, looking something like this. Adapted from Raymer, Daniel P. (1992). 12.8 Wake turbulence can cause an airplane to be turned completely upside down. 2.15 The standard unit of measure for static pressure for pilots and altimeter settings is: 2.17 At _____________ altitude the static pressure is about half that at sea level. I've made the recommended changes and have decent reverse thrust. Excess thrust is the difference between the total drag of the aircraft, and the thrust output of the powerplant. Now, to simplify things a little we are going to use a common substitution for the dynamic pressure: We will also define the lift coefficient in terms of lift and weight using the most general form where in a turn or other maneuver lift may be equal to the load factor n times the weight. And they may be different still in climb. Maximum excess thrust occurs: For a jet-powered airplane, at approximately the maximum lift/drag ratio (L/D MAX). One way to find the maximum ratio of y to x on any graph of y versus x is to extend the axes of the graph to include the origin (0,0) and just run a line from the origin to any point on the curve and find the point on the curve where the slope of this line is the steepest, just as was done in these related answers: What is the typical climb angle Power required to overcome induced drag varies, Power required to overcome parasite drag varies, Maximum rate of climb for a propeller airplane occurs. 8.23 For a power producer, unaccelerated maximum velocity will occur at the intersection of the full power-available curve and the ________________.

For the prop aircraft Raymer defines TOP as follows: It should be noted here that it is often common when conducting a constraint analysis for a propeller type aircraft to plot the power-to-weight ratio versus wing loading rather than using the thrust-to-weight ratio. 1.16 An airplane weighs 8,000 lbs and is flying at 6,000 ft altitude and an airspeed of 200 fps. 13.25 If an aircraft maintaining a constant bank angle increases its airspeed while maintaining a level, coordinated turn, what will the effect be on the radius of the turn?

The cruise based calculations mentioned above would give us valuable design information for our airplane based on a desired cruise speed and altitude for a design weight and would tell us the wing area and thrust needed for that cruise condition and the thrust needed to cruise at a desired maximum speed. 10.13 A higher density altitude on takeoff does not affect which one of the following aircraft below its critical altitude? The standard RoC formula (using FPM and LBS) usually shows the excess HP at sea level at max gross to be around 33% of the rated HP for most GA propeller aircraft. @quietflyer: Yes, this requires another arithmetical operation because airspeed is the vector sum of vertical and horizontal speed. -- why?

Highest point on the curve yields maximum climb rate (obviously). Represent a random forest model as an equation in a paper. Absolute Ceiling- This is the maximum density altitude that the airplane is capable of attaining or maintaining at max gross weight in the clean configuration and max continuous power. Note also that the data point you use for your trig calculation of climb angle can come from anywhere along the straight line you've drawn from the origin of the graph. Excess power is power available minus power required. 8.6 Propeller aircraft are more efficient than jet aircraft because, They process more air and don't accelerate it as much, 8.7 Turboprop aircraft are classified as power producers because. This is not a condition which we have studied earlier but we can get some idea of where this occurs by looking at the plot of drag versus velocity for an aircraft. <> Another factor to consider would be the desired maximum speed at the cruise altitude. 5.5 Laminar flow airfoils (NACA 66-XX series) are designed for the airflow to remain laminar much further back from the leading edge than on the conventional airfoils. Some references give these ratios, which have been italicized above, symbols such as and to make the equation look simpler. 12.6 The best way to control airspeed is with the ___________, while the best way to control altitude/descent rate is with the ____________.

Best Rate of Climb The cruise ceiling is the altitude at which the maximum climb rate is 300 ft/min Definition - Combat Ceiling The combat ceiling is the altitude at which the maximum rate of climb is 500 ft/sec or 2.5 m/s. The more efficient a plane is in things like cruise the lower its value of T/W. In other words this equation is really an energy balance. Interesting airplane; looks like Vy is more than double Vx! The essence of all this is that if we even have only three primary design objectives; a cruise specification, a climb requirement, and a takeoff or landing constraint, we can end up with three different values for wing area and thrust required for a given aircraft weight. 10.20 One of the dangers of overrotation is ________________. The question is; is there some way to analyze all of these at the same time and come to a decision about optimum or reasonable compromise values of weight, wing area, and engine thrust without having to go through iteration after iteration? 7.18 Increasing the weight of a thrust-producing aircraft moves all points on the thrust-required curve ____________.

The limit is a sailplane with T/W = 0 and at the other extreme we have fighter aircraft where T/W approaches unity. c. How did you infer those two answers from a pie chart? This ratio is a measure of aerodynamic efficiency as well as a measure of the way the structure is designed. 1. Power required is drag multiplied by TAS. A light wave has wavelength 500nm500 \mathrm{~nm}500nm in vacuum. One way to resolve this issue is to write our equations in terms of ratios of thrust at altitude divided by thrust at sea level and weight at altitude divided by weight at takeoff. Find the Drift Angle. Any combination of W/S and T/W within that space will meet our design goals. 1.17 An airplane weighs 8,000 lbs and is flying at 6,000 ft altitude and an airspeed of 200 fps. 6.25 Endurance is _____________ fuel flow. 1.14 An airplane with a mass of 250 slugs accelerates down the takeoff runway with a net force of 3,000 lb.
