Script to append files with same part of the name

I have a bunch of files (> 1000), which content has columns of numbers separates by space. I would like to reduce the number of files by appending the content of groups of them in one file.

All the files start with "*time_NUMBER*" followed by a number, and the rest of the filename (*pow_....txt*). For example : *time_0.6pow_0.1-173.txt*

I would like to append the files with the same NUMBER in a single file and make it with a script since I got ~70 different NUMBERs.

I have found 

cat time_0.6pow_*.txt > time_0.6.txt

it works but would like to make a script for all the possible NUMBERs.

Regards

You can do it like this:

for fName in time_*pow_*.txt; do
    s="${fName#time_}"
    cat "$fName" >> time_"${s%%pow*}".txt
done
