The first part of this experiment involved testing three wing designs in a wind tunnel. First, the wind tunnel was turned on with nothing inside and the flow velocity was recorded. Then, the first airfoil, a pre-built standard NACA 0024, was tested. It was put in the wind tunnel in the 0° slot on the Kelvin Lift & Drag Balance arm and locked in place. The balance was then calibrated so that the LIFT value read zero, and the wind tunnel was turned on to its high setting. Once the wind tunnel reached

a symmetrical aerofoil subjected to varying angles of attack. Pressure readings were taken at different points on the upper and lower surface of the aerofoil. The report concludes that maximum lift is generated between 12 º -15º, which is also the stall point. It also states that region close to the leading edge contributes most to the lift force. Introduction: This experiment is designed to measure the static pressure distribution around a symmetric aerofoil, find the normal force and hence to determine

The company Embraer has made a major investment in the Phenom 300. It’s “design life is 28,000 cycles or 35,000 hours, assuring it will have a 30- to 40 year economic life even with heavy economical use” (Pilot Report). In order to have a more reliable aircraft Embraer improved the Phenom 100 to produce the Phenom 300. The Phenom 300 contains a trimmable horizontal stabilizer to provide a better pitch control, and fly-by-wire multifunction spoilers. These panels “provide pilot-commanded inflight

was used to calculate the Reynolds Number which equated to 119366. Discussion The graph in Figure 3 confirms the theory stating that as the angle of attack of an aerofoil increases, the lift force it experiences also increases until it reaches stall position. The graph clearly shows the lift coefficient steadily increasing with angle of attack. This is due to the fact that as that as angle of attack increases, the point at which the airflow separates into streamlines going above and below the

Case Study Maria G. Andrade Safety 320 Flight 8284 from Empire Airlines was conducting an instrument only approach arriving at Lubbock Preston Smith International Airport (LBB) in Lubbock, TX where the aircraft impacted just short of the runway on 01/27/2009, approximately at 4:37 am. The aircraft, employed by Empire Airlines provided cargo services and was registered to FedEx Corporation (National Transportation Safety Board [NTSB], 2011).

ABSTRACT Helicopter is known for being extremely challenging to fly. The helicopter flight controls enables the pilot to attain a controlled flight. The flight controls differ drastically when compared to the fixed wing aircraft. The advancement in flight controls namely fly-by-wire system has resulted in reducing the complexity of the system. The state of the art fly-by-wire system has resulted in increasing the performance and at the same time reduces the workload of a pilot. The four main controls

Changing the measure of camber, or bend, present in an airfoil is an effective method for controlling the strengths and minutes that it creates under liquid stream. Moreover, the control power gave is huge regardless of the possibility that lone a humble part of the airfoil harmony can change camber. This is the situation with trailing edge folds, which make camber change through revolution of a discrete segment of the harmony, regularly the last 20-30%, in respect to whatever remains of the airfoil
