The recent Farnborough Airshow has driven the biggest ever monthly increase in aircraft orders, according to aerospace trade organisation, ADS Group.
It said orders were estimated to be worth between £135 and £155bn to the UK, providing nine years' worth of work.
The boost, which brings the total backlog to 12,000 aircraft and 21,000 engines, would, ADS said, offer "valuable stability to this wealth-producing sector and the many hundreds of thousands of people it employs".
It added: "These new orders reflect long-term industry growth projections which forecast a demand for more than 29,000 commercial airliners between now and 2032 as airlines look to grow or improve their fleets to cater to rising passenger numbers."
Paul Everitt, chief executive of ADS Group said: "As an important event for the global aerospace industry, we expected to see a peak in orders during the Farnborough Airshow. However, the volume of firm orders placed throughout July was unprecedented; adding almost 650 aircraft and 1,100 engines an already robust order book.
"Looking to rest of the year, we expect the focus to shift to maximising production and delivery numbers. Already this year, we have seen the number of aircraft being delivered increase significantly, putting us on track for a record-breaking year for aircraft deliveries, contributing more than £10bn to the UK already this year."
