the main topic, the Vortilon, a simple stall prevention device that was developed based on shared experience and is now freely integrated with all new aircraft entering the intensely price and performance-sensitive market.
In today’s cutthroat competition between airlines, only those airlines operating the entire gamut of air and ground operations at optimum efficiency will survive. The principal contributor to an airline’s bottom line is the quality of aircraft it operates. The same competition exists between the manufacturers as well, with an identical base criterion, i.e., the quality of aircraft they produce. Essentially, the governing factor is the maximum number of passengers that can be flown the longest distance in one trip with the minimum consumption of expensive aviation fuel in each category of aircraft─ short, medium, long and ultra-long range. “Every Kg. of basic aircraft weight saved is a million dollars saved over a life span of twenty-five years,” according to Dr. Kota Harinarayan, Project Director, LCA, India, my mentor in aerodynamics (1986) (n.p.).
Designing an aircraft and sections thereof take millions of man-hours from the drawing board to first flight to fully operational status. Aircraft have to be sleek and light, its surfaces as smooth as a baby’s skin, no unwanted drag creating protrusions, etc. Everything is centered about minimum weight, minimum drag and optimal use of CAD/CAM in the field of aerodynamics to extract maximum lift at minimum engine thrust in flight, with highest passenger density. Any aerodynamic innovation is most welcome.
I do not propose to look at ground operations like ticketing, loading, salaries, etc. That leaves only the aircraft. Here, there are two factors to be considered, the engine and the airframe. Since this Paper is specifically aimed at an aerodynamic concept, I will discuss engines only in brief. NASA (2008) describes four propulsion systems: The Propeller, the Ramjet, the Rocket and ...

These are depicted at Figure 1. Figure 1. Airfoil Forces Lift increases with the square of speed. This is shown by the lift equation: Lift= CL x (? p V2) x wing area (s), where CL is the coefficient of lift and p (rho) is density (Dole and Lewis, 2000). Assuming that in level flight, CL, p and s remain constant, then as speed is increased lift will increase.
Performance is influenced by factors including weight, available thrust, altitude and aerodynamics of the aircraft. Efficiency refers to the range or endurance of an aircraft per unit of fuel, known as specific fuel consumption (SFC), or fuel flow per pound of thrust (Dole and Lewis, 2000).
Construction of tall buildings have become the symbol of progress in all infrastructure expansion programs across the world. Further, in addition to the conventional engineering analysis required for the design of any building system, tall buildings
However, for the DHL Airbus – 300, the cause of the accident was a missile fired from the ground that struck the tip of the left wing of the plane (Indyakudimahan, 2009). The other difference was that the crew of the DC – 10 were unable to control the plane as they
Similarly, there are three types of stability: positive, negative and neutral. According to Skiba (2002), positive stability restores the aircraft to its original position after a disturbance, negative
Mathematic formulas aids in derivation of the total drag force of the aerospace.
Computation of drag loss entails approximation of the Shuttle’s mass at maximum time q. Shuttle mass is a function of time and normally derived from the propellant
The search results helped at obtaining information for and against the winglet design. The findings show that the winglet design helps in saving fuel, but only under some special conditions during flight. Hence, it means that an improvement
It is also defined categorically as the speed designed by the airplane manufacturer under the set standards and certification criterion that a plane can operate on one engine only while still the pilot maintains control of the plane. That is it is the technique
