Raytheon's Hawker Horizon is an all new `super mid size' corporate jet.
Design work on what became the Horizon was already underway when Raytheon Corporate Jets and Beech merged in early 1995 to form Raytheon Aircraft. The new design, initially labelled PD376 and later Horizon 1000, was one of three projects the new Raytheon Aircraft was working on, along with what became the Premier I. Raytheon worked closely with potential customers for the replacement for the Hawker 1000 in the design definition stage, and their input directly influenced the direction of the new aircraft.
Raytheon formally announced the Hawker Horizon immediately prior to the National Business Aircraft Association's annual convention in November 1996. The Horizon is due to make its first flight in late 1999, followed by certification and first deliveries in the northern spring of 2001.
One of Raytheon's design philosophies in developing the Horizon is to combine the earlier Hawkers' popular characteristics with advanced technologies. Experienced Hawker designers formed the core of the Horizon's design team and the aircraft has been deliberately designed to look and feel like a Hawker.
Compared to the Hawker 1000 the Horizon will have a wider, slightly longer fuselage with a flat floor and stand up headroom and a two tonne heavier max takeoff weight. The Horizon will feature an all composite fuselage which will be manufactured using the automated fibre placement technology developed for the Premier I. The composite fuselage saves weight and increases cabin volume. The empennage features an aluminium sub structure and carbonfibre skin.
Power will be from two digitally controlled Pratt & Whitney Canada PW308A turbofans. P&WC is a risk sharing partner in the program, as is avionics integrator Honeywell (the Horizon will feature Honeywell's Primus Epic avionics suite with five flat panel colour LCDs).
The Horizon's new metal construction supercritical 30o sweep, aft loaded wing will be built by Fuji Heavy Industries of Japan, another risk sharing partner, and will pass beneath the fuselage. Other risk sharing partners include Messier-Dowty (landing gear), Sundstrand, Vickers and AlliedSignal (APU and environmental control system).
