Flight Definition and 364 Threads

Was hoping someone could help me out with a question. It was on a online test and wasnt sure how to do it. The question was as follows: The no-show rate for passengers with reservations on a flight run by wizair is 16%. The next flight has 42 reservations. Find the probability of there...

So we need to make a practical report and I'm not sure how to do it. I've learned the basics like lift equals weight and thrust equals drag.. and then the teacher made a model wind tunnel in class, we then got air speed(km/h) and its mass(g) etc. for it then we had to convert them to life and...

With 9/11 fast approaching I became aware from a radio talk show that Nationally syndicated Mike Smerconish is raising money, 100% of which will go to building a Memorial in Shanksville, PA in memory of those who gave their lives trying to prevent the hijackers from reaching Washington, DC. I...

I understand how a pressure differential caused by an altitude change can cause temporary pain, but can it actually cause a lasting infection? There are two suspected cases in my entourage.

I'm very unfamiliar with energy-use in aviation, but I am wondering about what effect altitude has on parameters such as gravity (i.e. weight of the aircraft) and air-density, which I would think affects friction and combustion as well as lift. One thought I've had is that higher velocities...

This has been bugging me for 30 years, so I hope someone here can help. I was at the base of a local Dam that had a fish hatchery on top, and a HUGE flock of hawks circling above, waiting to get lucky. Yum! In a totally non-PC way, I started throwing rocks at the hawks. My 'lead' on them was...

Homework Statement An airplane in a wide "outside" loop can create an apparent zero eight inside the aircraft cabin. What must be the radius of curvature of the flight path for an aircraft moving at 749 km/h to create a condition of weightlessness inside the aircraft? Assume the acceleration...

hey, I was reading Aircraft Design: A Conceptual Approach by Raymer and i came across the following line. ' The aerodynamic efficiency of an aircraft, expressed as the lift to drag ratio is greatly reduced during low level, high speed flight as well is its engine efficiency. ' Can someone...

I'm interested in calculating the flight performance of World War One aircraft. The aerofoils can give me the coefficient of lift, we have the engine horsepower and the maximum level speeds. Wingloading can generate the stall speeds. How do I calculate the minimum horse power required for...

Research Proposal: Sub-Orbital & Orbital Flight Path *Brain-storm Ideas With Me* *Light "imagineering" should be okay on this thread. I don't require anything that technical, mostly just ideas.* I'm in a technical writing class which is giving me the opportunity to work on grant...

Hi everyone! I'm a newly admitted student for graduate studies. I'd been interested in Aerodynamics, especially in flight control, since I met with a professor who studies granular flow. Now I think granular flow is pretty cool and it's in its infancy nowadays. There are lots to discover and...

Homework Statement An airplane of mass 1280 kg has an engine failure when flying with an airspeed of 135 km/h at an altitude of 2590 m on a calm day. It then glides at a constant glide angle (which is the direction of flight below the horizontal) towards a safe landing at this constant speed...

The following is a paper I wrote mainly to collect my thoughts and document some research I did about interstellar space flight. The main ideas for this paper grew out of the things I always hear people talk about (blueshifted radiation) but I never see the math behind it, so I developed a few...

As a tennis player, I'm interested in the effects of top spin in tennis. I've done some research, but find myself somewhat confused about the concepts. (my questions assume the ball has top-spin) Magnus force & separation wake: in what direction do they act? do they act straight...

Homework Statement A rifle is used to fire two bullets. The first shot is at an angle of 60° above the horizontal and the second at an angle of 45° above the horizontal. The speed of EACH bullet as it leaves the rifle is 200ms^1. For EACH bullet calculate the horizontal range and the...

Hopefully this is the right forum. I'm trying to do something I think should be straightforward, which is to describe a straight and level flight over a WGS84 Earth in ECEF coordinates. For example, pick a starting lat,lon,alt,heading and speed and just keep going at that heading and altitude...

Was given this problem as a homework assignment but I would like to solve it...just need a push in the right direction. An airliner is cruising at a ground speed of 450 knots. A flight attendant, serving drinks, accidentally knocks a bottle off her cart. The distance from the top of the...

Russia's new First Flight of the T-50 http://news.yahoo.com/s/ap/eu_russia_stealth_fighter As someone who grew up in the time of the Soviet Block why am I surprised this looks like a combination of the F-22 and the Northrop F-23?

Here is a video of a BO-105 getting put through its paces. I remember seeing the German Army every once in a while flying these. They are pretty cool little helicopters. This is pretty close to the UH-72 (EC-145) that we are in the process of replacing the OH-58 with. Rigid rotors are pretty...

hi I wonder if anyone can help me to tell any sort of website about how a plane flies? thanks

Homework Statement A prince trapped in a castle wraps a message around a rock and throws it from the top wall with an initial velocity of 12 m/s [42 deg above the horizontal] the rock lands just on the far side of the castles moat at a level 9.5m below the initial level. determine the rocks...

I have been involved in a discussion concerning the behavior of a bullet during flight. It seems there are long distance shooters who expirence a better MOA at 300+ yards than at 100 yards. The theory pit forth is that when a bullet leaves the muzzle, it is not stable in its flight. This lack...

Imagine separating a parabola into its different x and y components and linking them by the component of time. Scenario: Given: Gravity No Drag The velocity of the launched object is not sufficient to escape the gravitational pull. Ignoring: The change of gravity as the distance...

Is this statement correct? As a bullet flies, it loses forward velocity MUCH faster than it loses rotational velocity. If a barrel rotates a bullet 1 turn in 10 inches. Would it not exit rotating at the same rate regardless of velocity? Understanding as velocity is increased the RPM will...

Hello everyone, During the last few days I've been working to solve a "small" problem I hope someone here might be better at than I am. I'm writing a function that returns the state vectors of an orbiting body of neglible mass based on the orbital elements semimajor axis, semiminor axis...

This is not homework, I'm just curious. Perhaps it belongs in the Engineering Forum, but the last one of these I posted there just got left in the dust. I have a rather specific question to ask those of you who are familiar with paper airplane building/structure/dynamics. How would I go about...

Hello all. I'm modelling several new aircraft as mods for a flight sim. These mods are all WW2 birds like the Kittyhawk and Ta152. The generic computer models have a series of terms I am unsure about. So far I've been using existing aircraft modelling as a guideline but as we are expanding...
