Re: Blackburn B-48 Firecrest
Design
Operational experience had found that Blackburn's Firebrand strike fighter to be far from suited to carrier operations.
Particularly, the pilot sat behind the wing trailing edge, looking over a very long and wide nose, which gave a particularly poor view for landing.
In October 1943, Blackburn's design staff, lead by G.E. Petty, started work on a devlopment of the Firebrand, with a redesigned wing and improved pilot view, which lead to [Vous devez être inscrit et connecté pour voir ce lien] being issued by the [Vous devez être inscrit et connecté pour voir ce lien] on 26 February 1944 covering the new aircraft.
The new design, the Blackburn B-48, was known unofficially by Blackburns as the "Firecrest" but always known by its Specification number by the Air Ministry and Navy.
The Firecrest had a redesigned, inverted [Vous devez être inscrit et connecté pour voir ce lien] of [Vous devez être inscrit et connecté pour voir ce lien] and moved the pilot forwards and raised his position so that he was now looking over the leading edge, and down the nose, rather than along it.

Four [Vous devez être inscrit et connecté pour voir ce lien] were fitted to give good low-speed handling for landing and the wing had retractable [Vous devez être inscrit et connecté pour voir ce lien] on both surfaces.
The wing folded in two places to allow storage in carrier hangars.
In other respects, the Firecrest was a conventional monoplane design with a tailwheel undercarriage and particularly clean lines.
The first prototype was rolled out in February 1947, and made its maiden flight on 1 April that year.
By this time, however, the Air Ministry had concluded that the Firecrest would not be adequate for the Strike role, for which the [Vous devez être inscrit et connecté pour voir ce lien] was preferred, and work on the complete but unflown second and third prototypes was suspended in November.
Later in the month, however, the third prototype was allocated to tests of powered [Vous devez être inscrit et connecté pour voir ce lien] controls, as testing of the first prototype had shown that while adequate at cruise speed, the ailerons were heavy both at low and high speed.
The second prototype was allocated to structural testing.

The third prototype made its maiden flight in early 1948,
While the Firecrest was faster than the Firebrand, and gave its pilot a much better view from the cockpit, it was otherwise disappointing, with[Vous devez être inscrit et connecté pour voir ce lien] claiming that the Firecrest was even less manouverable than the sluggish Firebrand, while the powered ailerons gave lumpy controls, leading to instability in turbulent air.
The Firecrest had been rendered obsolete by the arrival of [Vous devez être inscrit et connecté pour voir ce lien] engines, and while Blackburn did draw up proposals for [Vous devez être inscrit et connecté pour voir ce lien] powered derivatives of the Firecrest, but these were unbuilt, with orders going to Westland for the Wyvern.
The two flying prototypes remained in use until 1949, being sold back to Blackburn in 1950, and were later scrapped.
