NASA initiated the Variable Sweep Transition Flight Experiment (VSTFE) to establish a boundary layer transition database for laminar flow wing design. For this experiment, full-span upper surface gloves were fitted to a variable sweep F aircraft.

Role of Freestream Disturbances. Before initiating the flight test program, the authors were conducting laminar flow control experiments on a swept wing at the Illinois. 1) In the helicopter experiment, what was the independent variable The independent variable was the folding of the blades in different directions.
Remember the independent variable is the variable that the experimenter changes, usually followed. Abstract. This paper discusses and evaluates the test measurement techniques used to determine the laminar-to-turbulent boundary-layer transition location in the F variable-sweep transition flight experiment (VSTFE).
An F aircraft was modified to become the test bed aircraft for the variable- sweep transition flight experiment (VSTFE) program. The VSTFE program is a laminar flow program designed to measure the effects of wing sweep on boundary layer transi- tion from laminar to turbulent flow (refs.
1 and 2). The F aircraft was selected. NASAan F Navy Tomcat, seen here in flight, was used at Dryden in and in a program known as the Variable-Sweep Transition Flight Experiment (VSTFE).
This program explored laminar flow on variable sweep aircraft at high subsonic speeds. An F aircraft was chosen as the carrier vehicle for the VSTFE program primarily. A design study for a supersonic business jet with variable sweep wings is presented.
A comparison with a fixed wing design with the same technology level shows the fundamental differences. It is concluded that a variable sweep design will show worthwhile advantages over fixed wing solutions.

Flutter Clearance of the F Variable-Sweep Transition Flight Experimen t Airplane-Phase 1 Author: Michael W. Kehoe Subject: NASA TM Keywords: Flutter, Ground vibration test, Modal Analysis Created Date: 9/5/ PM. Circadian Rhythms and the Human covers the basic principles behind the human circadian rhythms.
This book is composed of 12 chapters that discuss the detection, analysis, and definition of rhythms, specifically exogenous and endogenous rhythms.
This book also demonstrates the mechanism of metabolic and gastrointestinal rhythms. This book is a miracle. The miracle is that the author lived to write it. 'Corky' Meyer joined Grumman in the s when that company was demonstrating its ability to design and build Navy fighters such as the Hellcat and Bearcat (and, later, other types of Naval aircraft and civilian flying boats), and went on to undertake flight test of essentially every significant Grumman fighter /5(19).
This program explored laminar flow on variable sweep aircraft at high subsonic speeds. Flight transition data applicable to swept wings at high subsonic speeds was needed to make valid assessments of the potential for natural laminar flow or laminar flow control for future tranports of various sizes operating at various cruise speeds.

The use of a variable wheel is a technique that students can use to graphically represent the factors involved in an experiment.

His description, alone, of his flight-test experience of the variable-sweep XFF-1 Jaguar and its appalling difficulties (it was a significant contributor to the F Tomcat, technically) is worth the price of the book, but any page you look he describes, often with profound candor, the lot of the test pilot before (and this is crucial in /5.
Design of a Swept-Wing Laminar Flow Control Flight Experiment for Transonic Aircraft Michael J. Belisle,1 Tyler P. Neale,2 3Helen L. Reed, and William S. Saric4 Texas A&M University, College Station, Texas, This paper addresses the conceptual design of a flight-test experiment incorporating a laminar flow.
Physics Lab 2 3. Estimate uncertainty – particularly watch for the greatest source of uncertainty. Record your data in a table if appropriate. If you do either experiments B or C, make a GA plot with the independent variable on the x-axis (angle, height, ball diameter) and the dependent variable on the y-axis (range, initial velocity).
Most inventions in aerodynamic design are represented—from the delta-wing and wing-body airplanes of the familiar Concord and B-2 stealth bomber to the lesser known variable-sweep. Twenty-five years before the Ames-Dryden AD-1 ScissorsWing experiment, (see left) and most probably a major inspiration for the same, this Messerschmitt Me-P was being developed in February as yet another 'last ditch' WWII effort to thwart the Allies.
The Messerschmitt Me-P research aircraft tested a wing that could pivot fore and aft to form oblique angles up .Lift Experiments. Here are some simple experiments to demonstrate Newton and Bernoulli Lift: Newton Lift.
