Small Jet Airplanelight aircraft
However, before Honda was willing to make an investment in a new offspring and line of products, Honda had to test designer variable under realistic circumstances. "Fujino remembers, "In order to test our approach in experiments, we looked all over the globe for a windtunnel. National Transonic Facility, NTF for short, at the Langley Research Center, was the clear option.
The NTF was opened in 1983 with the aim of helping develop the larger planes that were being made. lt wasn't that nobody had windtunnels. However, none of them solved an important problem: the model aircrafts used for the tests were much smaller than the actual ones, often up to 50x smaller, while the ambient molecule had the same sizing.
The HondaJet was NTF-tried to see if the computer model of its cutting-edge over-the-wing power bearing was working correctly in actual flight or not. In order to partly adjust these Reynolds number differences, the NTF, like several other windtunnels, is pressurised so that the compression of the atmosphere is proportional to the size of the airplane.
In order to be able to simulate large aeroplanes, however, this pressurisation is not sufficient to fulfil the flying requirements. In order to complete the work, the NTF can also inject clean nitrous oxide at ambient temperature up to -250 F, which further enhances atmospheric pressure to further emulate the actual airplane height experiencing operating environments. There the agency also experimented with innovation in airplane construction - some of which, like the singlet, have become standards in today's jet.
Hondas aircrafts has the second kind of deal bargained for, says Wahls. Most of Fujino and his crew had already sketched their planes, but had to carry out the last tests. While Fujino says that the test enabled him to select the best among several option for the cowling of the overwing motor bearing arrangement, it mainly demonstrated that the current layout worked as anticipated.
Honda established its General Aviation affiliate Honda Aircraft in Greensboro, North Carolina, where 1,700 people are engaged in the production of the airplanes. One of the most important innovations of the new jet is the powerplant bracket above the wings, a big difference from earlier lightweight jet engines, which usually install the powerplant on the trunk, the airplane's primary part.
Installing the powerplant above the wings can disrupt the airflow, but Honda's NTF-tested NTF developed a " DOT " concept that actually reduces the shock wave and thus the aerodynamic resistance. Lower aerodynamic resistance also improves the jet's propellant economy, making the aircraft more economical to fly than other lightweight aircraft.
It is estimated that Honda Aircraft's powerplant setup consumes up to 17% less propellant over a given range than standard aircraft setup under similar flying and operating condition and operators. Installing the powerplant above the wing also improves passengers' ride quality, says Fujino: "There is more room in the cab because the motor takes up no room and vibration is not transmitted, which reduces hissing.
It sells to pilot operators and small businessmen who have to go a lot.
