Este Pudo Haber Sido Un Excelente Avión...PIRANHA 6

...Y nos hubiera venido bárbaro algo de este tipo. Un avión chico, monomotor, relativamente econónomico de mantener, moderno, modular y construido por los suizos (buscaban socios para hacerlo en el momento en que apareció en Aeroespacio la nota, hace algunos años ya). Tal vez se hubiera podido participar con ellos, en esos días todavía circulaba el SAIA 90. Por la topografía del país originario del proyecto, hubiera sido seguro de despegues y aterrizajes cortos, con dientes de primera, bien equipado de electrónica y ya estaría disponbile y funcionando. La variante Piranha 6 estaba destinada a superioridad aérea e interdicción. Era precioso.
Copio una nota y características.

Piranha 3

The PIRANHA project was undertaken by ALR as a private venture with the support of Switzerland’s industry. The reason for initiating the project was that the development and manufacturing cost of advanced tactical fighter aircraft (F-15, F-18) has risen so high that the number of aircraft which an armed service is able to procure has been reduced to unacceptably low levels.


PRIANHA 1 was a subsonic aircraft configuration optimised for the anti-armour and anti-helicopter roles.

PIRANHA 6* was designed to meet the battlefield air superiority and battlefield interdiction roles. These role requirements led to a very small, agile supersonic fighter powered by advanced engines such as the RB.199, EJ-200, or M.88.


The design works undertaken in the early eighties have been applied by ALR in other projects.

A competent and largely professional group in Switzerland has devoted much time and private money to promoting an attractive lightweight fighter in the belief that there is a large (3,000-4,000 units) global market for such aircraft. Many of the advantages of a small fighter are obvious: lower costs of acquisition and ownership, lower training costs, higher serviceability, reduced vulnerability in combat and probably enhanced agility, and many others.
At first the Piranha was as small and simple as possible, and an early propulsion choice was two Larzac M74-07 augmented turbofans. This gave way to the RT.172-58 Adour, and pressure of increased mission demands and higher performance has now forced concentration on the R B199 with the GE F404 as a second choice. Inevitably this puts the Piranha squarely into the same class as the superficially similar JAS39. How, then, can this private proposal hope to succeed?
ALR would reply that their project is even smaller and simpler than the Swedish aircraft, and also offers significant advantages over the F-20A Tigershark and other existing aircraft. It has a flapped canard and wing trailing-edge "flaperons" all controlled by a digital FBW system, though the dogtooth wing leading edge is fixed. By 1984 the wing had grown in size from the 16m2 of all previous studies to the figure given above, to achieve higher sustained and instantaneous turn rates. If ever an unofficial fighter project deserved to succeed, this does, if only for the decade of effort behind it.
 
Muchos aún hoy dicen que el Gripen se inspiró en el fustrado Piranha y a ver por el diseño y las prestaciones me parece que algo de razón hay.

y del F-20 tambien, es cosa de ver como Ericsson estuvo metido en ese
proyecto y como mucha de la avionica esta inspirada en el aporte sueco,
para que decir el radar, que basicamente es el APG-67 mejorado.

saludos.

Yo al Gripen le veo una inspiración directa en el Bae P106B - P112 :rolleyes: .

El Gripen es a todas luces un Viggen moderno,
es una opinion personal.

puede que si en su fuselaje, pero en cuanto a concepcion de un avion barato
de mantener, con poco personal de tierra y mas aun, en su electronica, radar
y otros conceptos de diseño, sigo viendolo como lo que el F-20 pretendia ser...

Ericsson formaba parte de ese proyecto, en donde ante el interes de Taiwan
de contar con el F-20, pero con la explicita capacidad para usar AIM7, se
necesitaba que alguien proveyera el CWI y los gringos acudieron a Ericsson.

De hecho Suecia tambien estaba interesada en el F-20 antes de decidirse a
desarrollar el Gripen...
