Frank Whittle : biography

1 June 1907 – 9 August 1996

The Air Ministry still saw no value in the effort, and having no production facilities of its own, Power Jets entered into an agreement with steam turbine specialists British Thomson-Houston to build an experimental engine facility at a BTH factory in Rugby, Warwickshire.Nahum 2004, p. 53. Work progressed quickly, and by the end of the year the prototype detail design was finalised and parts for it were well on their way to being completed, all within the original £2,000 budget.

Financial difficulty

Earlier, in January, when the company formed, Henry Tizard, the rector of Imperial College London and chairman of the Aeronautical Research Committee (ARC), had prompted the Air Ministry’s Director of Scientific Research to ask for a write-up of the design. The report was once again passed on to Griffith for comment, but was not received back until March 1937 by which point Whittle’s design was well along. Griffith had already started construction of his own turbine engine design and, perhaps to avoid tainting his own efforts, he returned a somewhat more positive review. However, he remained highly critical of some features, notably the use of jet thrust. The Engine Sub-Committee of ARC studied Griffith’s report, and decided to fund his effort instead.

Given this astonishing display of official indifference, Falk and Partners gave notice that they could not provide funding beyond £5,000. Nevertheless the team pressed ahead, and the W.U. (Whittle Unit) engine ran successfully on 12 April 1937. Tizard pronounced it "streets ahead" of any other advanced engine he had seen, and managed to interest the Air Ministry enough to fund development with a contract for £5,000 to develop a flyable version.Nahum 2004, pp. 37–38. However, it was a year before the funds were made available, greatly delaying development.

In July, when Whittle’s stay at Cambridge was over, he was released to work full-time on the engine. On 8 July Falk gave the company an emergency loan of £250, and on the 15th they agreed to find £4,000 to £14,000 in additional funding. The money never arrived and, entering into default, Falk’s shares were returned to Williams, Tinling and Whittle on 1 November. Nevertheless, Falk arranged another loan of £3,000, and work continued. Whittle was promoted to Squadron Leader in December.

Testing continued with the W.U., which showed an alarming tendency to race out of control. Because of the dangerous nature of the work being carried out, development was largely moved from Rugby to BTH’s lightly used Ladywood foundry at nearby Lutterworth in Leicestershire in 1938, where there was a successful run of the W.U. in March that year. BTH had decided to put in £2,500 of their own in January, and in March 1938 the Air Ministry funds finally arrived. This proved to be a mixed blessing – the company was now subject to the Official Secrets Act, which made it extremely difficult to gather more private equity.

These delays and the lack of funding slowed the project. In Germany, Hans von Ohain had started work on a prototype in 1935, and had by this point passed the prototype stage and was building the first flyable design, the Heinkel HeS 3. There is little doubt that Whittle’s efforts would have been at the same level or even more advanced had the Air Ministry taken a greater interest in the design. When war broke out in September 1939, Power Jets had a payroll of only 10 and Griffith’s operations at the RAE and Metropolitan-Vickers were similarly small.

The stress of the continual on-again-off-again development and problems with the engine took a serious toll on Whittle.

He suffered from stress-related ailments such as eczema and heart palpitations, while his weight dropped to nine stone (126 lb / 57 kg). In order to keep to his 16-hour workdays, he sniffed Benzedrine during the day and then took tranquillizers and sleeping pills at night to offset the effects and allow him to sleep. Over this period he became irritable and developed an "explosive" temper.Nahum 2004, pp. 79–80, 89.
